I have a scenario where my office need to connect to another client office vpn using pptp. My office is connected to internet via router and a sonicwall firewall. Say PC1 in my office in the LAN will dial to client server and establish the vpn. This PC1 will be connected 24/7 VPN with client. Now my question how can I allow other PCs (say for eg PC2 and PC3) on the LAN to share the vpn on PC1 whenever they needed it to access the client server. Also while accessing the VPN the Local access as well as the internet should not be disconnected.
