Our company currently utilizes Staffmark for staffing the production floor. We have a Staffmark representative who is on site 80% of the time. He has his own office, and 2 computers that he requires use of. His office has no direct connection to our internal network for the obvious security reasons. Instead, we rely on a direct external connection with the local Cable ISP. This connection passes through a Linksys BEFVP41, which routes the traffic to both his computer, and the application terminal located in his office. Both require a connection to the same VPN at Staffmark, and both utilize the same authentication.
Connecting to the VPN is fine from both computers. When attempting to connect both to the VPN at the same time, however, causes the first to get booted. My research indicates that this is a known limitation with the router only allowing 1 VPN client to connect through it at any one time.
I am aware of the BEFVP41's ability to connect directly to multiple tunnels at once, and allowing any combination of the LAN access to any of these tunnels. However, it seems that the Staffmark VPN utilizes a username and password to authenticate the user. The router does not support this type of authentication, and instead utilizes keys, and other "real" types of authentication.
Would a VPN connection between the 2 sites be possible? I have attempted contacting Staffmark's technical support, but am unsatisfied with the answer. I could be deluding myself into believing that this connection is possible. Has anyone run into a similar issue and resolved it? Or should I give up the fight, and just order the second external line for the application terminal?
