Hi chaps I'm sure this is a straightforward and easily answered question. The environment is: --$DMZ_NIC- 192.168.1.0/24 mail,DNS,WWW servers / INET -ppp0-FW \ --$LAN_NIC- 192.168.0.0/24 LAN workstations I'm trying to get the LAN to be able to NBT browse the boxes in the DMZ, but they won't. I'm permitting all TCP and UDP from LAN to DMZ and back again ... It looks like NetBIOS isn't going to and from eth0-eth1. Is there some obvious Windows networking rule I'm missing? I've got TCP and UDP forward to and fro rules for eth0 and eth1 set up... Any suggestions gratefully received!
