Hi all, I have a problem with susefirewall2 and I hope somebody could help me. I have a leased line (2mbit, dedicated ip) to the net, a dmz and a local lan with a lotus server. I would like to receive mails from the internet for my domain which should come in and be forwarded to the smtp server in the dmz which will forward them to the lotus server. So here's a graph for that: inet | | server1, 3 network devices eth0: 192.168.100.1 (link to LAN) eth1: 192.168.50.1 (link to DMZ) eth2: 193.X.Y.Z (link to net) | | |-------------------server2, 1 networkcard (192.168.50.2) | running mail service (sendmail) | and apache web server | | | server 3, 2 network devices | eth0: 10.0.49.10 (link to LAN) | eth1: 192.168.100.2 (link to server1) | V in the lan: lotus server Currently mails come in and are forwarded to a sendmail server which is running on the server2 (dmz). From there they should be forwarded to server3 and finally to the lotus server (and vice versa). I tried to configure susefirewall2 in the way that connecting to port 25 on server1 forwards automatically to the dmz one or if it comes from the dmz to the server3 (and from there to the lotus server). But when I try to connect to 192.168.100.1 (port 25) from the server 3 and to 192.168.50.1 from the dmz I get the error messages "connection refused" although I opened the ports and did some redirect rules. Maybe somebody could have a look at my attached config file I currently have absolut no clue what might be the reason for this misconfiguration. Bye + thanks a lot, Werner
