I can confirm the problem, I have upgraded from 10.04 to 12.04 and pptp based vpn stopped working.
What I did : I did copy the '/etc/ppp/chap-secrets' and '/etc/peers/name_of_the_company' from the old setup to the new machine. In the older release the pppd call was all I needed to do , but now : Connecting is ok : $ sudo /usr/sbin/pppd nodetach call name_of_the_company Connect: ppp0 <--> /dev/pts/4 CHAP authentication succeeded MPPE 128-bit stateless compression enabled local IP address 10.10.116.34 remote IP address 10.10.116.0 other terminal : $ ping 10.10.16.162 -- no response $ route -n |grep ppp0 10.10.116.0 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 $ sudo route add -net 10.10.16.0/24 ppp0 $ route -n |grep ppp0 10.10.16.0 0.0.0.0 255.255.255.0 U 0 0 0 ppp0 10.10.116.0 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 $ ping 10.10.16.162 PING 10.10.16.162 (10.10.16.162) 56(84) bytes of data. 64 bytes from 10.10.16.162: icmp_req=1 ttl=252 time=124 ms regards, bq -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/953861 Title: network-manager-pptp forgets to add a route when connecting to (split) VPN To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-pptp/+bug/953861/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
