Let me clarify, since I think my original post was long and scary to people who might be interested :P My LAN setup is like so: ( internal lan ) - switch - hades (gw/nat box) - ( outside world ) In order to IRC from a machine in my internal network, and allow DCC to work, I used ipnat rdr rules[1], and tircproxy. This solution worked beautifully until I upgraded to FreeBSD 4.5-STABLE Friday afternoon. In order to eliminate the problem as much as possible, I setup netcat to listen on localhost:6999 (while tircproxy was not running), and tried to make use of the redirect (tried to connect outbound), I see the following while watching in ipmon: 03/02/2002 12:04:58.221667 @7 NAT:RDR 127.0.0.1,6999 <- -> 206.167.75.78,6661 [10.10.0.10,3704] 03/02/2002 12:05:22.249178 @7 NAT:RDR 127.0.0.1,6999 <- -> 206.167.75.78,6661 [10.10.0.10,3705] However, netcat doesn't receive any connections, and my windows machine reports "connection timed out". [gregp@hades] /home/gregp: nc -l -p 6999 -s 127.0.0.1 -vv listening on [127.0.0.1] 6999 ... ... However, telnet -s 10.10.0.1 localhost 6999 does connect and work fine. Is something wrong with how ipnat is redirecting my connection?
