to add a new ARP address to the WAN...
1.) on the menu under firewall select NAT
2.) Select the server NAT tab
3.) click the plust icon
4.) in External IP enter the additional WAN ip address here.
5.) Do enter a description.
6.) Select Save
7.) Select to apply changes

Now go do a proxy ARP so your upstream gets an ARP from your firewall
and thus routes traffic to you. (unless of course you have a subnet
directed at you from the upstream and then this is moot.)
1.) Under Services on the menu select Proxy ARP
2.) Click the plus icon
3.) Select single address
4.) Enter the same address you use in step 4 in the process above
5.) description, use one.
6.) Save
7.) Apply Changes

Okay you are all set. Now if you want to do outbound natting to this IP
you will need to manually setup those rules. Otherwise the firewall will
use the outbound NAT to the primary WAN IP address. What we did will
work for inbound traffic no problem, just make firewall rules allowing
those redirections... see previous post for those directions.
