[Bug 266598] if_ovpn(4) DCO module not supporting correctly IPv6 Traffic Class for tunneled packets
Date: Mon, 26 Sep 2022 09:04:29 UTC
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=266598 --- Comment #9 from Gert Doering <gert@greenie.muc.de> --- (In reply to Kristof Provost from comment #7) I have now tested a bit more. It's... interesting. Sending a packet with ToS 0x10 (fping6 -O 0x10) into an ovpn(4) interface will properly transmit the encapsulated packet to the remote host *but* "tcpdump -n -i tun7" will not show the packet. Receiving a packet with ToS 0x10 on an ovpn(4) OpenVPN peer (encrypted packet coming in from LAN) will neither show the packet on tcpdump, nor receive it into "FreeBSD stack". Based on this I have now built a t_client test that will excercise ping tests with ToS 0x10, so I can automatedly test if it works or breaks. Thanks for the challenge :-) -- You are receiving this mail because: You are the assignee for the bug.
