Are there any OSX admins out there?

I am helping a friend with a MAC OSX server who is trying to multilink multihome 2 NICs and 2 public IPs. One IP is from cable the other is DSL.

Most examples so far, uses multilink multihoming in LAN w private ip ->Internet scenarios with instructions to: 1) duplicate the en0 interface, 2) Rename interface, and 3) add second IP address info.

The interfaces are active, routing table info seems OK, DNS works, BUT virtual host in apache assigned to 2nd IP address is not answering external requests.

Somewhere, in the volumes of information read, I slightly remember references to "divert" in the firewall rules or "fwd".

Have anyone tried and succeed using multilink multihome on MAC OSX using cable and DSL?

1. solved

en0 is configured with IP 192.168.1.15

Destination Gateway Flags Refs Use Netif Expire
default 192.168.1.1 UGSc 134 5 en0

ipfw add fwd 192.168.2.1 ip from 192.168.2.15 to not 192.168.2.15 out
