Public bug reported: After installing 18.04, I started to have VPN problems that were very erratic. Some things worked, some did not (including parts of out JIRA install's website work but not others). I traced this to MTU. The problem goes away if I set my MTU on the VPN interface to 1358. However, when I connect with openconnect -vvv, I see that the server side sets 1400. Additionally, 1400 works fine on the Mac version of Pulse Secure. I can't figure out what is going on or what could be different. This worked fine in 17.10.
I am running 18.04 with all of the updates as of this week. ** Affects: openconnect (Ubuntu) Importance: Undecided Status: New -- 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
