Hi Lars Thank You for the answer. I was not sure how to set it up to avoid problems later... This was exactly what I was looking for. Jaska.
you end up with
extern-ADSL-intern
| 192.168.33.42
`- 192.168.33.1 - SuSE FW - 192.168.77.254 / \ 192.168.0.254 DMZ / \- 192.168.77.1 - server1 LAN \- 192.168.77.2 - server2 box1 - 192.168.0.1 -/ \- 192.168.77.3 - server3 box2 - 192.168.0.2 -/ box3 - 192.168.0.3 -/
both DMZ and LAN may be distinct class C networks you of course can choose otherwise, and use 10.2.4.8/16 for the DMZ, if you like :)
hth,
