Hi James! > I am using EigersteinB2, dynamic IP, on a Cox@home cable modem. The box is > a Pentium 120, 32 megs of RAM.

The problem, if it's what I think it is and I'm quite sure it is would only show up with a dymanic IP... > Using the stock EigersteinB2 image, modifying /etc/network.conf to forward > SSH from external machines through the firewall to the internal server at > 192.168.1.210 seems to work properly, but when I uncomment (and correct the > internal IP) on the line to forward IMAP, and add either "0/0_imap" or > "0/0_imap2" to the line defining external TCP ports, and then reboot, I get > the following error message.

When that part of the scripts run, EXTERN_IP is not defined, the command being incomplete the port forwarding command fails in this way... With a static IP address EXTERN_IP is always defined so you would not have this problem... > Am I forgetting to do something else in network.conf or somewhere else? I don't use DHCP (I have PPPOE... )-; ) and my scripts have been somewhat tweaked so I can't be sure but have you set EXTERN_DHCP to YES? Setting it to YES will fetch the IP address of the external interface and store it in EXTERN_IP so it should (EXTERN_IP) be defined when the port forwarding rules are executed... Good luck!
