I have two separate networks. One is an MPLS network used for voice only between multiple sites. It is on a 192.168.2.x network. My data network is separate from my voice network. My data network is on a 10.0.1.x network. Our phone vendor now wants to gain remote access via Internet to access the phone system. To do this they need to connect to a particular PC through my data network. The MPLS network does not have Internet access but communicates between two other sites. My question is how can I get the PC to be accessible to my data nework for the vendor to access it through the Internet but also be able to connect to the MPLS network? I have a handful of routers that can be used.
