FC2 - NIC firewall?

[Dave Pisarek]

Is there a built in firewall in FC2 that stops certain traffic to the
NIC? sshd is running and i can ssh to the localhost but from outside I
cannot. The machine is assigned a static private IP and is behind 
Netopia router. the netopia is set to forward all traffic to the
static Ip of the FC2 machine but the connection dies when I attempt to
connect. does anyone know where I can check this in FC2?
