I have installed my first M0n0wall and I'm having problems with it. The
setup is as follows:
- 4 machines with public IP addresses in range a.b.c.d
- M0n0wall with LAN address in range a.b.c.d
- All 4 machines have M0n0wall LAN address as default gateway
- M0n0wall WAN address public IP w.x.y.z
I've added a rule to allow ssh from the WAN to the LAN from anywhere.
However, no matter what I try I cannot get ssh working from the Internet
to any of the machines. Logging on M0n0wall shows that the traffic is
accepted right to the machine, but blocked going back out. A tcpdump on
the machine verifies that it does see the incoming traffic, and that it
tries to reply.
All 4 machines can access the Internet without any problems, ie ssh,
http outbound seems to be working fine.
I've even tried opening everything, ie adding rules to allow anything
anywhere, but I still see the reply packets blocked.
I would really like to get this working as apart from this M0n0wall has
been a joy to work with.
