--- Comment #4 from Marek Zarychta <zarych...@plan-b.pwste.edu.pl> --- In my case, the limits for the successful "ping -4 -s $size remote_IP" are: - in IPv6 tunnel, $size is limited to 1400 - in IPv4 tunnel $size limit is 1412 It was tested between FreeBSD stable/14 running OpenVPN 2.6.10 with DCO and FreeBSD CURRENT running OpenVPN 2.6.9 as a client. It's not the case though. The problem I faced was too large TCP segments that couldn't pass the tunnel thus preventing SSH sessions from being established over tunnel. -- You are receiving this mail because: You are the assignee for the bug.
