--- Comment #2 from Marek Zarychta <zarych...@plan-b.pwste.edu.pl> --- (In reply to Gert Doering from comment #1) Thank you for your excellent guidance. Indeed, setting "tun-mtu 1400" on the server fixed the issue. As discussed on IRC, I will leave this PR open as a precaution. Perhaps mssfix will come to FreeBSD DCO at some point or it will get solved differently. -- You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.
