Hey guys, first I gotta say that I love m0n0wall.

We have had some problems with ftp servers however.

login works fine, but when you try to list, the client complains it
could not make a data connection.

I was wondering if you  are using the ip_conntrack_ftp module for iptables?

Just FYI, we are using NAT, and the firewall allows incoming tcp/udp
for ports 20-21.

We were not using the one-to-one mode, but in doing so, and opening
some more ports, we were able to resolve the issue.

Just wondering if I can get some thoughts back on this.

Sorry I dont have all the details handy, but I can get them tomorrow at work.
