Thank you. I suspect it has to do with the randomized source port. but as far as I can tell, I've found the setting for that. but apparently not. at this point I spinning my wheels in a rut and out of ideas for new things to try.

I'm trying to setup a server behind a Fortigate firewall. I have the port opened to the proper device and can access game from. within the network but cannot figure out what I'm doing wrong. Has anyone ever setup with a Fortigate? is there anything special I need to do that I might be missing?
