I always used to be able to host my SA:MP Server off my old PC on the Router in my house. It always worked fine, however upon switching to a new PC I can no longer see the Server via my external IP address, but I can on the local (i.e. the server is running but not getting to the internet).
I have tried after disabling all firewalls including Avast and Windows Firewall. Its something on the PC, not the router/ports, because it worked fine before. Also, the Server folder is as-was with the old PC, and runs fine on 127.0.0.1.
Any ideas?
