Tim Shannon, from the comment about network-manager-openconnect-gnome, please use this updated patch to build the network manager. I added conditions for the cisco GRE and GRETAP link types, see https://en.wikipedia.org/wiki/Generic_Routing_Encapsulation and http://www.cisco.com/c/en/us/td/docs/security/security_management/cisco_security_manager/security_manager/4-4/user/guide/CSMUserGuide_wrapper/vpgredm.html#69194 so I think this might fix the issue connecting through network-manager-openconnect-gnome
Please build the network-manager with the following patch and see if DNS leaks are fixed over cisco openconnect VPN links. Thanks! ** Patch added: "possible cisco network-manager-openconnect-fix" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1624317/+attachment/4890352/+files/resolved-vpn-dns-leak-fix.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1624317 Title: systemd-resolved breaks VPN with split-horizon DNS Status in systemd: New Status in network-manager package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: I use a VPN configured with network-manager-openconnect-gnome in which a split-horizon DNS setup assigns different addresses to some names inside the remote network than the addresses seen for those names from outside the remote network. However, systemd-resolved often decides to ignore the VPN’s DNS servers and use the local network’s DNS servers to resolve names (whether in the remote domain or not), breaking the split-horizon DNS.
