I don't know. That would need a special proxy. Try searching the IP Filter mailing list for more info. The problem is you are losing information. You map a bunch of private IPs to a single public IP, so there is no way of knowing which of the internals the remote server is trying to connect to. As far as the remote server is concerned, all of the traffic is coming from the NAT box. =09=09=09Fer > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
