I have to install a vendor workstation on our network that I would like to isolate from the rest of our WAN. The workstation does not need to connect to any of our systems and only needs to be able to make a vpn connection with the vendors equipment. In the past we have built vlans for these types of machines and then created access lists on the switch that only allows the workstation to access its vpn peer ip, but this doesn't seem as secure as it could be.
could a GRE tunnel between the router at the site and our edge router or something similar work better in this situation. I think ideally we could provide that workstation with a public ip at our edge so it couldn't see anything within our network.
