Yes, I found that one also. However, I am not sure how to set it up correctly: Assuming natd is running on nathost on port "natd 4665/divert" and I want to redirect tcp connections going to host1:port1 in real to host2:port2. host2 is connected to fxp0. First the ipfw statment: ipfw add divert natd all from any to any via fxp0 Or do I have to use ipfw add divert natd all any to host1 via fxp0 And the the natd line: natd -n fxp0 -redirect_port tcp host2:port2 host1:port1 I have tried around a little bit and I see packets going through natd (when run with -v), but the connection never succeeds...
