Firewall/NAT

It would be a very handy feature to be able to run TFTP traffic through m0n0.  As it stands, there is no way to do it.  Port forwarding will not do it because a host responds to a request on a random, usually unpredictable port or range of ports.  Most linux firewalls use a conntrack module to accomplish this.  I have been told that ip chains does not support this.  Any ideas?

Depends on the FTP client. For mine, I could set it's "response IP" to that of m0n0wall, but yes, those ports. I was able to narrow my FTP client ports to a small 100 range, then forward that back through m0n0wall and it all works fine.  Not sure if your TFTP supports that or not, but it's certainly possible to figure passive FTP to work through m0n0wall.
