For me the issue occurs with Juniper SSL VPN. Apparently network manager adds the original default route, I'd guess upon DHCP renew, which overrides the default route that should go to my VPN tunnel (from /var/log/syslog):
NetworkManager[xxx]: <info> Policy set 'xxx' (wlan0) as default for IPv4 routing and DNS. The network-manager-vpnc package seems to integrate with network-manager in a way that prevents network manager from doing this as with VPNC to a cisco concentrator, the issue does not occur: NetworkManager[yyy]: <info> Policy set 'yyy' (tun0) as default for IPv4 routing and DNS. What would be required to achieve the same with Juniper SSL VPN? Is there a way to prevent NM from doing these policy updates? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991666 Title: VPN Connects Successfully & Then Shortly Thereafter Fails To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-pptp/+bug/991666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
