I'm having a similar issue I just upgrade to 15.10 from 14.04 and I started having the same issue. I would connect from the CLI using vpnc- connect and my saved profile. However once connect I would not be able to access any resource on the other side of the tunnel. It appeared to be a routing error but I had no way of confirming that.
In an effort to solve this I installed nm-applet-vpnc and connected with it and everything worked correctly. I took a look at the routes using netstat -r and there was a sicrepancy. netstat -r after connect from CLI $ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default 10.0.0.1 0.0.0.0 UG 0 0 0 wlan0 10.0.0.0 * 255.255.255.0 U 0 0 0 wlan0 link-local * 255.255.0.0 U 0 0 0 wlan0 <TUNNEL IP> * 255.255.255.240 U 0 0 0 tun0 <MYPORTAL> 10.0.0.1 255.255.255.255 UGH 0 0 0 wlan0 netstat -r after connect using nm-applet-vpnc $ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default * 0.0.0.0 U 0 0 0 tun0 default 10.0.0.1 0.0.0.0 UG 0 0 0 wlan0 10.0.0.0 * 255.255.255.0 U 0 0 0 wlan0 link-local * 255.255.0.0 U 0 0 0 wlan0 <TUNNEL IP> * 255.255.255.240 U 0 0 0 tun0 <MYPORTAL> 10.0.0.1 255.255.255.255 UGH 0 0 0 wlan0 I ran sudo route add default tun0 Now netstat -r looks correct Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default * 0.0.0.0 U 0 0 0 tun0 default 10.0.0.1 0.0.0.0 UG 0 0 0 wlan0 10.0.0.0 * 255.255.255.0 U 0 0 0 wlan0 link-local * 255.255.0.0 U 0 0 0 wlan0 <TUNNEL IP> * 255.255.255.240 U 0 0 0 tun0 <MYPORTAL> 10.0.0.1 255.255.255.255 UGH 0 0 0 wlan0 And now everything is working correctly. However it would be much preferred to not have to manual add the default route once the vpn connection is up. FYI janl I can get the nm-applet-vpnc to prompt me for dual factor authentication. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1513437 Title: Incorrect default routing after vpnc completes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-vpnc/+bug/1513437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
