I run 2 public networks with different routers and IPSs
All my servers are multi-homed.

1) confing both IPs
you set up each network on your interface.

2) config your routing (2 choices)

2a) kernel with ipfw and "options IPFIREWALL_FORWARD"

$fwcmd add pass all from ${network_a} to ${network_a} via ${ext_if}
$fwcmd add pass all from ${network_b} to ${network_b} via ${ext_if}
$fwcmd add fwd ${gw_a} ip from ${myip_a} to any
$fwcmd add fwd ${gw_b} ip from ${myip_b} to any

2b) with pf

pass quick on $ext_if from $network_a to $network_a no state
pass quick on $ext_if from $network_b to $network_b no state
pass out quick on $ext_if route-to ($int_if $gw_a) from $myip_a to any no state
pass out quick on $ext_if route-to ($int_if $gw_b) from $myip_b to any no state

3) verify that you can use both ips for internet

traceroute -s $myip_a www.example.com
traceroute -s $myip_b www.example.com
