Hi All,

We are trying a project with DAM/DAT(Dynamic Address Mapping/Translation) support for linux. The machine should accept any preconfigured systems on the lan side and route them to the WAN (second ethernet port) like NAT.

The LAN machines shouldnt be in the same network range (subnet) like the router/DAM machine, but they need to get internet access.

Is there a way to implement a mechanism in linux for mapping those (ip- unknown) clients:

for example:

[ 192.168.1.200 ] \ [ 10.100.54.7 ] => [ DAM machine LAN side || WAN side PPPoE ] => { Internet } [ 192.168.0.5 ] //

All nodes are direct connected via ethernet.

Any solutions ?

Someone told me earlier theres a way for that to be done with MAC address routing instead of TCP/IP routing. But i didnt find any solutions about Layer2 to Layer3 Routing except any tunnels (or netbios etc).

Thanks.

Rukman Naik.
