I just set up 2 soekris-net4801-based m0n0wall boxes and everything works
fine, except I need some help troubleshooting the IPsec tunnel that I
created between them.
The tunnel is set up properly and I can ping between the two subnets
indefinitely, but all TCP connections (ssh, http) fail after exchanging a
few packets. For example an ssh connection will let me log onto a host
across subnets but it stops responding when I get to the shell prompt and
give a command such as "ls."
Using tcpdump, I just see the traffic stopping, nothing else. No messages
in syslog either.
Any ideas on how to proceed would be greatly appreciated.
P.S. I want to take this opportunity to let the developers know that they
are doing an awesome job. I started using m0n0wall last week and I am
thoroughly impressed with the quality of the project.
