ipfilter destination NAT

Michael Pye — Wed, 20 Jan 2010 00:58:32 GMT

linux has iptables with DNAT option. How do I do it with ipfilter ? I want to forward any outbound requests from hpux box that target any hosts on port 80 and port 443 to be forwarded transparently to a proxy ?

The rdr option only lets me NAT inbound traffic, not outbound.

Thanks for any suggestions.
Michael
