vb6 multiplayer server using playit.gg kindly assist - vb6

Question

I am new to this. am not sure if anybody used game ranger before and I am trying to create something more simple.
client and server connection, the client connects to the server pc over the internet using the
playit.gg provided ip:port and it connects ok.
now I wonder if there is anything else needed for the game to detect other ips in-game multiplayer screen?.
I have a multi-connection server and IP vb6 source. simple using Winsock.
were you see the server:port is inputted from
.RemoteHost = "write-mechanical.at.playit.gg"
.RemotePort = "55224"
chat client side to connect
Option Explicit
Private Sub cmdConnect_Click()
'Check input.
txtServer.Text = Trim$(txtServer.Text)
txtPort.Text = Trim$(txtPort.Text)
txtNickname.Text = Trim$(txtNickname.Text)
If Len(txtServer.Text) = 0 Or Len(txtPort.Text) = 0 Or _
Len(txtNickname.Text) = 0 Then
MsgBox "Please fill in all fields!", vbCritical
Exit Sub
ElseIf Not IsNumeric(txtPort.Text) Then
MsgBox "Invalid port value!", vbCritical
Exit Sub
End If
'Done with that...
strMyNickname = txtNickname.Text
With frmChat.sckClient
.Close
bolRecon = False
.RemoteHost = txtServer.Text
.RemotePort = txtPort.Text
.Connect
End With
Me.Hide
frmChat.Show
AddStatusMessage frmChat.rtbChat, RGB(128, 128, 128), "> Connecting to " & txtServer.Text & ":" & txtPort.Text & "..."
End Sub
Private Sub txtPort_KeyPress(KeyAscii As Integer)
'Number only.
If Not IsNumeric(Chr$(KeyAscii)) And Not KeyAscii = 8 Then KeyAscii = 0
End Sub
and server-side to accept

just a quote from my comment laying out what I want to do.
the server is in my computer running and they connect to me from
another house over the internet using the ip and port provided by
playitt.gg ok so now that i know they are connected to my machine via
the server app. now i want to know is will multiplayer games be able
to detect those ips even we got same game same version installed
