https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=286263 --- Comment #1 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> --- It looks more like OpenVPN issue, not ovpn(4) module problem. For unknown reasons, Opnvpn disables DCO for the connection. Here's the difference between the sessions initiated from the dual-stack-capable kernel and an INET6-only kernel: 50c50 < tuntap_options.disable_dco = ENABLED --- > tuntap_options.disable_dco = DISABLED 107c107 < comp.flags = 24 --- > comp.flags = 152 298c298 < DCO version: FreeBSD 14.3-PRERELEASE #6 (...)MINTAKA6ONLY --- > DCO version: FreeBSD 14.3-PRERELEASE #24 (...)MINTAKA 335c335 < TUN/TAP device /dev/tun0 opened --- > DCO device tun0 opened 349,350d348 < Outgoing Data Channel: Cipher 'AES-256-GCM' initialized with 256 bit key < Incoming Data Channel: Cipher 'AES-256-GCM' initialized with 256 bit key 365c363 < Closing TUN/TAP interface --- > Closing DCO interface -- You are receiving this mail because: You are the assignee for the bug.home | help
