GM's machine barriers

Applies to : FGC (+ FGU in LAN mode)

Default ports : FG "Classic" = TCP 1802, FG "Unity" = UDP 1802

These first 3 points relate to the configuration of the GM's machine/OS.

Breaking these barriers should be enough to successfully host a game for players located in your own home network, even if you are in a no-go situation for remote player access.

If you have a third-party protection software installed, it may "take over" some settings from Windows 10 itself : you may then find them in the third-party software settings.

Barrier 1 : Windows 10 "public/private" network setting

Windows 10 has a setting to classify each network it is connected to as :

  • either "pubic" (read : "not safe")

  • or "private" (read : "safe")

Windows 10 will prevent incoming connections from "public" networks, including Fantasy Grounds, so be sure to tag your current W10 network connection as "private", or else...

Barrier 2 : OS-managed firewall

Be sure to allow incoming communications to your TCP 1802, or better yet to your Fantasy Grounds executable program in the operating system firewall, or else...

Here is an example of Windows 7 firewall rules authorizing any kind of incoming connection to the Fantasy Grounds program, with TCP+UDP protocols and the "ALL" value for networks, adresses and ports parameters (W7 Firewall "advanced" view) :

TODO : W10 screenshots needed here

I would advise authorizing the Fantasy Grounds program ("Classic" and/or "Unity") for ALL incoming connections, instead of specifically TCP 1802 (FGC) or UDP 1802 (FGU).

TODO : Other screenshots needed here ??

That will enable using alternate ports for use cases like "multiple FGC+FGU games with 1 VPN server" - see and following sections.

Barrier 3 : Third-party protection software

If you are using any kind of third-party anti- malware/virus/threat protection software, chances are that you also need to enable incoming communications for FG in these, or else...
