Cannot connect to my LFS Server

[Cola]

Okay, I just checked the settings on the router. Both TCP and UDP are open.

Could it be a problem from my friends side? When he tries to connect to the host, he gets Client connect: Connect failed.
He tried setting up a host as well, when I tried to connect, I got the same error.

One thing I noticed in the router settings, was that I could check both "Portudløsning" which translates to Port triggering/release OR I could check "Port videresendelse" which translates to port forwarding.
The settings we have set, are both checked to Port triggering/release, should it be forwarding instead?


If it's for any good, I've got a Netgear WNDR3700 router.
