I'm not absolutely certain, but I'm fairly sure. The behavior changed when I installed 18.04, which was relatively recently compared to its release date. For a couple of months, I'd try to use it for a few months, remember it was wonky, and need to get work done before the end of the train trip. Finally was on a longer one the other day where I went hunting for the solution.
I can't be sure what the MTU was set to back when it was working/on 17.10 (I suppose I'll find out by installing that version), but the fact remains that the MTU that /does/ work with the MacOS version does not work with OpenConnect on 18.04. I'm not sure what could be different between the two. Anyway, will followup. If there's any useful output to provide, let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814502 Title: VPN does not work with MTU of 1400 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openconnect/+bug/1814502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
