Fios Static IP Woes

I'm hoping that someone can help me with this one. Days of googling turned up no answers for me.

At my workplace, we have a dual wan setup with Cable and Fios internet. We have a block of 5 static IPs with each service. The router I'm using is a ZyXEL USG 200. In it, I configured a 1:1 NAT for the Fios public IPs to map to my servers. These basically mirror the settings for cable which are working. The firewall is set up using the WAN group which both the WAN interfaces are part of, so I know that the firewall is not the issue.

For whatever reason, the Fios static IPs will not route to the servers I need them to for anything. The only solution I have found is to put a switch between the ONT and router and connect the servers directly to that and configure them with the static IP. This is not an option for me. If anyone can help, it would be greatly appreciated.

Did you follow the directions in the USG 200's manual for 1:1 NAT?

looks pretty straight forward.

Just saw this the other day maybe it could help you if you wanted to hack it together.

I'm thinking you may need a Policy Route to specify each machine to route traffic in and out of the specified WAN port(s).

mwarps - That is exactly what I did. The 1:1 NAT works perfectly on Cable.

Liger88 - This looks promising. I'll mess around with it.

Thank you for the replies.

Update: Creating the virtual interfaces per the link didn't seem to work the way I want it.
