Installed new copy of White Russian with x-wrt on a Buffalo WHR-HP-G54.
Can't get port forwarding working 100%, just partially.

When /etc/config/firewall contains:

   forward:dport=21:192.168.0.100:21
   forward:dport=8082:192.168.0.102:8082
   forward:dport=45678:192.168.0.100:45678
   forward:dport=45679:192.168.0.102:45679

Line 1 FTP server can be accessed from the LAN but not the WAN,
Line 2 WWW server can be accessed from the LAN but not the WAN,

Line 3 uTorrent works fine, client can be seen from WAN and LAN,
Line 4 uTorrent works fine, client can be seen from WAN and LAN.

I know I'm missing something simple. Some forwards work, others do not. Any suggestions appreciated.
