If you can configure also other side of the tunnel, I'd try to have both IPs from same network but it probably doesn't matter. Also I'd remove 'proxyarp' which IMO should be on the other side of the tunnel if you want to access other computers in remote network since it should pretend your IP is him to computers in that network. But both options should not be fatal. Can you also try to ping your n770 from the other side? I'd guess it can be also misconfiguration on the other side. I'll try to connect via PPTP too and attach a log. Also when seeing 'pty' in the output there is a low limit on the number of ptys being 4 so try to increase it just in case http://www.gossamer-threads.com/list...%20limit;#5027
