Hi there, I've been trying to route packets received on port xxxx via the external interface (used by NAT) of my FreeBSD gateway to the same port on a local machine. The manual would seem to make this simple stuff - I have added the following line to /etc/rc.conf: natd_flags="-redirect_port tcp 192.168.1.241:xxxx xxxx" accessing this service on the local machine via the local address is fine but a port scan from the outside, reveals that the relevant ports appear closed still. Needless to say - the service is unavailable. I have tried entering the following on the command line (with and without the /etc/rc.conf flag): natd -redirect_port tcp 192.168.1.241:xxxx xxxx but here's what i get: natd: aliasing address not given I have tried adding the external address as follows but to no avail: natd -redirect_port tcp 192.168.1.241:xxxx XXX.XXX.XXX.XXX:xxxx To avoid confusion I am running with an open firewall - rules below: gatewayb# ipfw list 00050 divert 8668 ip from any to any via ep0 00100 allow ip from any to any via lo0 00200 deny ip from any to 127.0.0.0/8 00300 deny ip from 127.0.0.0/8 to any 65000 allow ip from any to any 65535 deny ip from any to any I have read quite a few mails from people finding the same problem but not yet found an answer. My guess is that I am missing something simple but i've been banging away at this for a while now and no joy. Any advice would be appreciated.
