    The first requirement is that two computers, with two instances of the Software, have an internet connection. When you are Player #1 and your friend or girlfriend Player #2, for example, on both your computers: WIFI should be On.
    There are multiple configurations possible like in a multiplayer (2 players) game !
    When making the Connection together, with two programs of the same given Software title. Be aware of the fact you have to make that Connection very quickly because after Clicking [Connect] there is a time out interval of ca. 3 seconds waiting for the other to respond.
    Then try communicating for this verbally or by Smartphone or Whatsapp when doing this for making the Connection timed and right.

    Case #1

    [Connect]-ing two computers in a (Wireless) home network situation using KPN Modem Sagemcom box B12.

    First you may want to know what is possible and should happen, when a connection is established between two instances of such a Net Connect 4 Game over two Windows 10 or 11 systems. You can touch, or click with your mouse, let's say 'teleport' Game Play Data like this, in the following way:
    Player #1 turns on UPnP IGD in the KPN Sagemcom Experia box B12 Modem/Router. UPnP IGD must be enabled in the modem settings due to... the security ? It is possible for gaming according to the KPN (provider in the Netherlands) forum.
    Log in onto your Modem.
    Make a modem rule for portforwarding named Net Connect 4 in the Modem in the Netherlands with KPN glassfiber and make sure it is enabled.
    You will find portforwarding; it is found under the 'Beveiliging' (Security) menu once when you are logged in, in the Modem settings.
    Let's say in this way: you are Player #1, on the Laptop, your friend Player #2, on the Microsoft Surface Go 2 tablet computer.
    Then the rule: Player #2 is searching the host address of his or her tablet for filling in a new entry in the Modem portforwarding setting. Use CMD.EXE (search field on your taskbar) & ipconfig on your Windows Surface Go 2 tablet computer.
    You can fill in this entry for a modem rule on your Laptop with the system name of your tablet computer, use protocol: TCP, use port 1200, doel (target) then for example.. (when found the private range IP Address from that tablet) e.g. 192.168.2.5 .
    VPN should be disabled or OFF on both systems.
    Type this IP address in an Net Connect 4 instance in the inputfield for the IP Address next, don't hit Enter yet on your keyboard of that tablet computer.
    Confirm and Save the rule etc. And Log out of the Modem. You have to do these Modem Settings only once. I shall state this only once. It applies every case throughout the following testcases or Manual descriptions.

    Next Player #1 is searching, using Edge and ipconfig the (wireless) external host address on the WAN next, this will Player #1 fill in in the inputfield of his or her or program later, not hitting Enter yet, see below.
    Player #1 is typing in his or her inputfield on the screen with the keyboard the host IP address of the Laptop computer on the WAN. Find this at https://whatismyipaddress.com for example. This IP address of his or her computer of which he/she should have been writing it down earlier, remembering it from a note or by head.
    Player #2 is typing in the inputfield on the screen of the program on the tablet computer, of Player #2, .. the IP address found also in the rule (as the target address, dutch:'Doel' IP-ADDRESS which you made earlier in the Modem Settings) for your tablet computer (-name). This rule is the Modem rule made earlier on your Laptop and!?/or!? tablet computer.
    It is the tablet host IP address which Player #2 should have been writing down earlier, then remembering it for the purpose of making the Connection eventually later again with portforwarding in a second, third.. etc. time when you want to play Net Connect 4.
    Don't hit Enter yet.
    So that is the host address found while running CMD.exe (Command Prompt) and command: ipconfig[Enter] on your tablet computer as well, they should be the same in Net Connect 4 inputfield for the IP ADDRESS on that tablet thus !! They are identical.
    Both Players should click or touch: [Listen] now. Player #1 is counting 3..2..1.. fast & Player #1 touches or clicks with the mousepointer [Connect]. Shortly now, merely at the same moment, or within 1 or 2 sec. approximately later, Player #2 should do the same. Mind the order of actions described and the last clicking of [Connect] within the 3 seconds time out ?
    You did it.
    Result: Test Succeeded ! Connection established. Now the sentence 'Connection established' will be heard on the two systems at the almost same time and the Connected symbol/icon should appear also.
    Now both Players hit the Start button on the program on the two systems.
    Now the Players can Play Connect 4. Each drop a chip in the blue rack by selecting a column of the rack clicking or touching that column !
    Enjoy !

    Case #2

    [Connect]-ing the computer's Modem KPN Experia 10A Box over ADSL & the internet with your opponent (to an Online.nl Provider Modem, for example): within a city. Out of that city, or (with)in any cities, towns or townships is expected to function properly typically or normally too:

    Let's say: you are Player #1, your opponent Player #2..
    Fill in the Modem with Poort forwarding, nieuw item (or existing item, while repeating the test/procedure), LAN Host : the host address of the internal host as acquired in the way of Case #1 in my case it is 192.168.2.8 .. (use CMD.EXE & then ipconfig in order to get it again..)
    The rule for my opponent in his Modem remains the same like in previous testcase Case #1, as way ago was set for his Online.nl Modem (some years ago for NetMemory.exe, I believe)..
    Next my opponent Player #2 is looking up his external IP host address via..
  • Get to know your IP-address for the outside world : this he/her will send via WhatsApp or phone, with next his/her opponent is able to fill in later in his/her inputfield of the Program (IPV4 address).
    ..and sends this to Player #1 by means of Whatsapp or rather (smart)phone.
    I as in Player#1, will look up my external host IP address as well and do the same..
    Player #1 is writing down the external host IP Address of Player #2, which he or she sended. The just acquired address via Whatsapp or phone, from Player #1 & is written down by Player #2, for using in a future game later likewise..
    Next both Players touch or click, with their mousepointers, [Listen] , while Whatsapp- or (smart)phone line or connection is open.
    Next both Players will fill in the acquired external host IP addresses from their opponents in the inputfields of their Programs for a kind of endpoint IP addresses purpose.
    Next both Players touch or click, with their mousepointers, [Enter] , while Whatsapp or (smart)phone connection remains open for the verification later..
    Next Player #1 counts 3..2..1.. and touches or clicks [Connect] , with his or her mousepointer.
    Next Player #2 will shortly later also touch or click [Connect], with his or her mousepointer (for instance a 1 à 2 sec period later)..
    My brother, Player #2 and me, Player #1 are playing at this time..
    My brother wins this first game, A Four In A Row version, as a test application.
    Result: test succeeds ! (Full duplex connection established).

    Success !

    Case #3

    [Connect]-ing the computer & KPN Modem Sagemcom box B12 over glassfiber cable and the internet with your opponent:
    Player #1, in Access Control-->Portforwarding--, is enabling UPnP IGD on the KPN Sagemcom Experia B12 Modem/Router again..

  • Let's say: you are Player #1, your opponent Player #2..
    Fill in the Modem with Poort forwarding, nieuw item (or existing item, while repeating the test/procedure), LAN Host : the host address of the internal host as acquired in the way of Case #1; in my case it is 192.168.2.8 .. (use CMD.EXE & then ipconfig in order to get it again..)
    The following is essential: as I found in the page from the link above, the external host address remains empty and should be recognized as an asterisk: * later in the rule when saved & applied. Also turn this rule on if you made that rule before or if it was not turned on at this stage..
    The rule for my opponent in his Modem remains the same like in previous testcase Case #1, as way ago was set for his Online.nl Modem (some years ago for NetMemory.exe, I believe)..
    Next my opponent Player #2 is looking up his external IP host address via..
  • Get to know your IP-address for the outside world : this he/her will send via WhatsApp or phone, with next his/her opponent is able to fill in later in his/her inputfield of the Program (IPV4 address).
    ..and sends this to Player #1 by means of Whatsapp or rather (smart)phone.
    I as in Player#1, will look up my external host IP address as well and do the same..
    Player #1 is writing down the external host IP Address of Player #2, which he or she sended. The just acquired address via Whatsapp or phone, from Player #1 & is written down by Player #2, for using in a future game later likewise..
    Next both Players touch or click, with their mousepointers, [Listen] , while Whatsapp- or (smart)phone line or connection is open.
    Next both Players will fill in the acquired external host IP addresses from their opponents in the inputfields of their Programs for a kind of endpoint IP addresses purpose.
    Next both Players touch or click, with their mousepointers, [Enter] , while Whatsapp or (smart)phone connection remains open for the verification later..
    Next Player #1 counts 3..2..1.. and touches or clicks [Connect] , with his or her mousepointer.
    Next Player #2 will shortly later also touch or click [Connect], with his or her mousepointer (for instance a 1 à 2 sec period later)..
    My brother, Player #2 and me, Player #1 are playing at this time..
    ...
    Result: test succeeds ! (Full duplex connection established).

    Success !

    Case #4

    [Connect]-ing two computers (this can be probably achieved over the WAN (internet) also). One with KPN MODEM Sagemcom Experia box B12 with a MS Windows tablet computer via fiber and Wi-Fi hotspot to the other, a laptop, through an Android 9 mobile smartphone in home network situation (in this way over the internet is working also to your family, Friend or aquaintance!) for inter-connecting the data of chips play to and from the tablet for the Game to a laptop instance of the Game:
    Make sure that your resolution is set in such away that all elements fall within the frame, and that there is no overlap between the input field and 'the blue rack' or any elements in the Four In A Row version.
    'Player #1', in Access Control-->Portforwarding--, has turned UPnP IGD on again in the KPN Sagemcom Experia box B12 Modem/Router..
    ..
    Create a separate rule for a Memory Game x game or a Four-in-a-Row version in the Modem in the manner described in Case #1.
    Create a hotspot on your mobile smartphone over WiFi & connect the computer /tablet of 'Player #2' via the mobile smartphone over WiFi, the smartphone itself serves as a Wifi point (e.g. temporarily during the procedure of building up a connection and while playing later)..
    Next my 'opponent', 'Player #2' is looking up his/her IP host address op via..
    Automatic [DHCP] was ON. An IP address from the: Private Network non-overlapping range 192.168.xxx.xxx on his or her device..
    Look into (i) on your hotspot on your computer or tablet. Of you click (i), Network and Internet will appear. There you'll find the IP4 Address of your hotspot to your mobile. Click (i) --> Network & Internet
    (here comes an image of device #2 of 'Player #2' screenshot)..
    'Player #1', I ,also look up my external host IP address, in the usual way via a website or the Modem.
    'Player #1' notes the external host IP Address of 'Player #2', which he or she receives via Whatsapp or phone from 'Player #2' & 'Player #2' notes that of 'Player #1', for later use.
    Both 'Players' press or click, with their mouse pointer, then on [Listen], while Whatsapp or phone line is open in a situation over the internet.
    Both 'Players' enter the external IP addresses, which they have previously obtained e.g. by telephone from their 'opponent', in the input field as an end point or end device address.
    Both 'Players' press [Enter] shortly after each other (the Whatsapp or telephone line remains open for verification later, in a situation over the internet)
    'Player #1' counts 3..2..1.. if he or she has pressed or clicked [Connect] with his or her mouse pointer.
    'Player #2' also presses or clicks [Connect] (with his/her mouse pointer) shortly afterwards, e.g. 1 to 2 seconds later.
    'Player #2' plays and Player #1 also plays..
    Result: test passed! Connection accomplished. Success.

    Good luck! NB this test was done by connecting two devices of my own and 'supposedly' playing.. (with myself as a test)

    Case #5

    [Connect]-ing two computers...using two 4G hotspots on two mobile smartphones; a private one for my laptop and a work one for my MS Surface tablet computer. It is a bit the same as in Case #4 then, First in an at Home Network situation.
    Remember Net Connect 4 is full screen, so you might want to adjust resolution to: for example 1920 x 1080 on the tablet so there is no overlap of some input field elements with the blue rack.
    WIFI is OFF on my smartphones, mobile data is ON to make an internet Network connection, of course.
    VPN is OFF on both computers and on my Smartphone(s). WIFI is ON on the computer or tablet of 'Player #1' and opponent; 'Player #2', both seperately connected to the two mobile hotspots.
    Then use the two IP addresses of the private internet addresses range: 192.168.***.***, which you can find in the CMD Command Prompt on your system, this is so for both Players, for typing in the Net Connect 4 program instances IP Address field elements on the systems.
    For now let the cursor in the inputfield on both computers just blink On & Off.
    Press [Listen] on the laptop computer only, for example, so on one side of the connection to be established. Then [Connect], quickly simultaneously with the two (tablet) computers, to then establish the connection between the two programs more or less at the speed of light, or if you like like a battle out of the blue, while a large black 'link' symbol appears on both systems, within a maximum of 30 seconds after each other to the ultimate goal: to establish a stable connection. Simultaneously on both systems, otherwise a time-out is possible.

    Case #6

    [Connect]-ing two computers...using WiFi hotspot ON mobile smartphone over the WAN (internet). A bit the same as in Case #4 ..
    WIFI is ON, on the Windows 10 laptop or MS Surface computer(-tablet) of 'Player #1' at side A of the connection to be made & at side B of the connection to be made WIFI is ON too, on a Windows computer or Windows Surface computer tablet.
    WIFI is ON on my mobile smartphone, with the hotspot ON.

    Case #7

    [Connect]-ing two computers...using 4G hotspot on mobile smartphone: it is a bit the same as in Case #6 then, but differently in the way it's over the internet (WAN) ..
    WIFI is OFF on my mobile smartphone. Hotspot is ON. Mobile data is ON logically.
