gift gnutella doesn't work - please help a newb

i run a gift-server, it's also firewall and router, wins, samba, apache, ...
running gentoo linux

I cant use the gnutella network and dont know why!!!!

OpenFT & FastTrack work fine

Gnutella cant connect to any node, whats wrong?

Do i have to use a special port? (3312)
allow incoming tcp/udp on port from wan, INPUT chain? (DONE)
any special settings in giftd.conf or Gnutella.conf?
Maybe i have to update gwebchaches? how should i do this?

Please help!!! anyone experienced or with a running gift-gnutella?

I've found hothing helpful anywhere out there!
