Hey,
My VPN connections drops after about 15 minutes or so any ideas for some scrip to
re-run pppd every 15 min….???? I am not a Linux expert by any means ….. Any idea is
appreciated…. Gary-
Hi Gary,
Your connection is likely timing out. Try adding `lcp-echo-interval 6000` to your `options.pptp`. This will send an echo request every 6000 seconds to keep your connection alive. Adjust the number to suit your needs

Hi Dave,
Great tutorial, thanks…
Is it possible to define static DNS servers which are dynamically added passed to the resolv.conf when the PPTP connection is up? and are removed whenever the PPTP connection is down? -
How would you test that you are infact connected to the VPN?
I would want to test the IP address being give out from the PC if connected to a website or a P2P service. I am using a headless CLI only Debian machine.

Worked. Thank you Dave. :)

Can you please help me with my problem. VPN stopped to work, it only worked for once. No reboot was. I just changed the username and password for non-test credentials.

It looks like the client can’t access the VPN server in order to establish the connection. Typical cause of that problem is incorrect firewall or NAT configuration on the server, assuming the address is correct.
