It's... interesting. Sending a packet with ToS 0x10 (fping6 -O 0x10) into an ovpn(4) interface w= ill 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 pack= et 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 tes= ts with ToS 0x10, so I can automatedly test if it works or breaks. Thanks for= the challenge :-) --=20 You are receiving this mail because: You are the assignee for the bug.=
