Hi All!

For some reason while trying to open ports for p2p programs, the port is open only for UDP traffic and the TCP traffic is blocked (i.e. when opening port 5757 both for TCP and UDP traffic, when checking with a port scanning program i can see that the port is indeed open for UDP traffic, but TCP traffic gets blocked).

Im using an SL2-141 router which i had no problems with before, Win7 and Comodo Firewall (ive defined the ports on both firewalls, windows firewall is inactive). I ran the portscan with both firewalls shut down, both firewalls running and just one of them, and on all test ive got the same problems...

Can anyone tell me whats the problem and how should I fix it?
