Hopefully that's enough info on hardware and such


So my issue is as such,

I can run the server just fine, people can connect bots spawn and everything runs fine. Up until the point I try to connect (not on the same computer but on the same network) and it causes everyone to freeze and time out. Its only when I connect on a local connection though. Although nuclear dawn can run just fine even if I am on a local connection. So I am not sure what the issue is. I am fairly certain I have forwarded the required ports, I have even changed my client ip (was suggested by the steam support forum) but nothing seems to remedy this issue. I was able to run the servers just fine until about a month ago.

Thank you for any input on the matter
