Limiting browing when Samba on a gateway

[markus]

Hello JF

Can you figure out which "outside" service your
samba-gateway-multipurpose-machine is trying to connect to via the modem? It
might be that samba is unable to resolve the clients' netbios names and
tries to figure them out over DNS queries.
In that case set samba to act as WINS server or (if you have another WINS
Server in your domain) to resolve names at another server.
Disabling netbios-ssn and netbios-ns calls on the outgoing interface would
help as well (brute force, that is).

Hope it helps a little.
