If you have one of the larger builds of dd-wrt then you probably have PPTP support built into the firmware. This will allow you to move VPN connections to the router instead of having to connect from each desktop which will securely make the remote network seem like part of the local network.
One thing I have noticed is the Point to Point Tunnel Protocol (PPTP) connection can drop and isn’t automatically reconnected in at least some situations. Below are instructions on manually restarting from the shell of the router you are running dd-wrt on.
Stop DD-WRT VPN Connection:
- root@wrt54gs:~# /tmp/pptpd_client/vpn stop
Start DD-WRT VPN Connection:
- root@wrt54gs:~# /tmp/pptpd_client/vpn start
There are other options such as debug which could help troubleshoot the VPN connection via the command line. Below is a list of available options for the vpn command.
DD-WRT PPTP VPN CLI Options:
- PTPP VPN CLIENT
- start - Starts the Client
- stop - Stops the Client
- go - Run the Client interactively (for debugging)
- debug - Run the Client interactively (in full debug mode)
If the VPN connection drops restarting it is the easiest way to see if your issue is resolved.
