The issue is that the NAT Engine has to associate the GRE stream with each individual connection, but this is quite difficult as GRE doesn't have simple tags to identify the connection like TCP. The NAT engine doesn't know which client to send the GRE packet to. Unfortunately, this problem occurs in the NAT engine at the client end. If this doesn't support Multiple Session VPN Passthrough there is no simple fix. The solutions I have used for this are: - Replace Client router with one that supports multiple session VPN passthrough - Setup a site-site VPN from router-router so everyone shares same VPN connection - Arrange server end to allow VPN connection to a range of IP addresses and get each client to connect to a separate Ip Address. - Use a pool of IP addresses at the client end so that each client VPN connection appears to come from a separate IP address. - Give up and make sure only one person use VPN at a time.
