I have a need to allow NetBIOS/Network Neighborhood browsing across a firewall between one internal LAN segment (192.168.0.0/23) to another (192.168.10.0/24). The two networks are on interfaces eth2 and eth3, respectively, off of the corporate firewall.
The two segments of the LAN were seperated due to broadcast flooding during video streaming development work by a dev team. I have the majority of the instructions down, I *think*: iptables -t nat -I PREROUTING 1 -i eth2 -p tcp -d 192.168.0.1 --dport 139 -j DNAT --to 192.168.10.1:139 iptables -I FORWARD 6 -i eth2 -o eth3 -p tcp -d 192.168.10.1 --dport 139 -j ACCEPT iptables -t nat -I PREROUTING 1 -i eth3 -p tcp -d 192.168.10.1 --dport 139 -j DNAT --to 192.168.0.1:139 iptables -I FORWARD 6 -i eth2 -o eth2 -p tcp -d 192.168.0.1 --dport 139 -j ACCEPT Not sure if this should be Destination NAT or Source NAT. I would like advice and/or corrections from anyone out there that has a better knowledge of this, first. Thanks in advance.
