MPLS LAN port on Fat Pipe

I have a MPLS connection from my main building to a remote building.  The Cisco router has a VLAN with the IP address This interface connects to a HP core switch VLAN, which is behind the firewall.

We have two ISP coming into the Main Building, I just replaced my old load balance  with a new Fat Pipe. The Fat pipe has three WAN ports and one LAN port. The LAN port can answer to more then one IP address. As of now the LAN is connected to the outside interface of my firewall, using a pubic IP address. I want the MPLS traffic to pas thru the fat pipe but not the firewall.

I thinking I could connected the LAN port of the fat pipe to the VLAN on my core switch, and also connected the outside interface to the same VLAN,and added a IP of to the LAN port of the Fat pipe. That way MPLS 10.44.105.x will still be routed by the core switch and traffic going to the outside interface of firewall will just be pass to the firewall.  

But I am not sure this will work?

Thanks for any help with this problem.

your thinking is correct.

As long as you can run a vlan through the Fat pipe that stays on the inside (LAN) of your network you will bypass the firewall. also ensure that any routes you set up use the MPLS router as the default route to the remote network. If your inside network is not on the 10.44.105.x network you may need to establish a different vlan just for MPLS traffic and route accordingly
