pptp vpn logon problems
I have an ubuntu box running poptop. Configuration seems okey, because I can log on as long as I log on from another machine in the network - but when I try to connect to the vpn externally (tried from 3 different computers/places) I get a 691 error (specified port is not connected) after it has made the connection and tries to verify username and password.
From the logs on the ubuntu machine it looks like the LCP Config request never reaches the client - or that the reply never reaches the server. So I'm guessing it might be a routing problem since the ubuntu is behind an SMC router. I have opened port 1732 and 49 and tried to put it in DMZ, but I still can't logon externally. Code:
Jul 20 17:08:26 localhost pptpd[6373]: CTRL: Client 212.33.xx.xx control connection started |
Check the pppd logs
poptop uses protocol 49 (gre) which is different then TCP 49. What client/os are you using to connect to the poptop box. post your options.pptp file |
Tried both windows and linux to connect.
The linux clients behaves like the the server, sending LCP Config request without getting a reply (when connecting to the external ip, if it's in the network and can connect to the internal ip it works just fine): Connect: ppp0 <--> /dev/pts/1 sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x499f6437> <pcomp> <accomp>] --- repeated X times --- LCP: timeout sending Config-Requests My /etc/ppp/options file Code:
ms-dns 212.33.139.1 Code:
