Now, the logs are a bit different : May 16 22:58:14 mercure pptpd[1417]: MGR: connections limit (100) reached, extra IP addresses ignored May 16 22:58:14 mercure pptpd[1418]: MGR: Manager process started May 16 22:58:14 mercure pptpd[1418]: MGR: Maximum of 100 connections available May 16 22:58:17 mercure pptpd[1420]: CTRL: Client 88.190.22.113 control connection started May 16 22:58:18 mercure pptpd[1420]: CTRL: Starting call (launching pppd, opening GRE) May 16 22:58:18 mercure pppd[1421]: In file /etc/ppp/options.pptpd: unrecognized option '-chapms' May 16 22:58:18 mercure pptpd[1420]: GRE: read(fd=6,buffer=6124a0,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs May 16 22:58:18 mercure pptpd[1420]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7) May 16 22:58:18 mercure pptpd[1420]: CTRL: Client 88.190.22.113 control connection finished I'll try to dig a little on my side but if you have any clue... @Charlie: I tried to setup openvpn and experienced the same problem (as explained it was a network issue and not a pptp one). I would prefer to setup pptp because I want to connect a remote router that only manage pptp and not openvpn.
