But why would port forwarding be necessary? This isn't since i started using this internet, this is just out of no where == not a PF problem.
Something you can try is to restart your router by unplugging it, waiting 10 seconds, and plugging it back in. Then start your BL server. (UPnP should also be enabled on the server - there's no reason to turn it off)
Not to mention that a ton of people are having this same problem at the same time, one of those people is Elm, notice how the ping on that server he has up has been ---?
I can't go near the router
