I had the same problem, and I solved it putting in my options.pptpd configuration file as follow: lcp-echo-failure 30 lcp-echo-interval 5 This is to prevent timeouts in the client side, with the lcp-echo-faliure your server send echo request to the clients for respons when are an idle time, so you can modify this parameter to a higher value. I hope this will solve your problem, well, It was enough for me. regards.
