If you are actually using NetBEUI your options are: 1) bridge the traffic 2) Upgrade to NetBIOS/IP or SMB/IP If you are actually using NetBIOS/IP already, your options are: 1) setup a WINS server 2) create lmhosts entries on the client > I wrote the following iptable rule, but here all the traffic will be > directed from LAN2 to the domain controller on LAN1 > > Iptables –t nat –A PREROUTING –I eth1 –j DNAT –to-destination > 192.168.1.231 If you are using NetBEUI, your problem is not iptables. Your problem is you are using a non-routable protocol. As mentioned above, you need to use a bridge or switch over to something IP based. HTH, Chris
