More OpenBSD router problems.

I'm trying to set a gateway on a different subnet. I have a netgear router that goes to my OpenBSD box which has two NICs. I just reinstalled OpenBSD for a fresh attemp at a router. All i did was uncomment the nat stuff in pf.conf (and i replaced the $ext_if with rl0 and $int_if with rl1) and I turned in ip forwarding. I think i need a entry for the second subnet NIC, what exactly would that look like. At the moment the only thing the router will go to is a iMac running OSX. Could someone walk me through this.

The NIC that's plugged into the Netgear has to have an IP on the same subnet as what the Netgear assigns. The second NIC must have an IP on a subnet that does not overlap the one assigned by the Netgear. You can let the IP of the interface connected to the Netgear be assigned by DHCP, but the IP of the other interface will need to be statically assign so that the hosts connected behind it know what IP to use for their gateway.

$ man hostname.if
