thx for the reply, it's in the middle of our LAN due to the following reason.
This client has been connecting to these boxes via the tunnel we setup from our router to their router. So I can ping their subnet from the 4 boxes and they can ping our network/4 servers from their subnet. Their subnet is like 10.40.1.x or something.

They want to get rid of all these tunnels (they have over 15 offices, hence 15 tunnels were created from our site to their satellite offices). They brought in a MPLS setup so there's a router w/ 10.199.1.254 as the gateway sitting in my rack. Now we have to figure out how to route the 4 servers through this MPLS router and somehow for us to be able to connect to the box since we are fully responsible for them (os, hardware, app).
