I decided to do a watchdog script,
vxlan works fine.
One endpoint is an old 5$ raspberry 0, its
CPU is much happier with vxlan than with wg.
Thanks again

Ah, so it's an existing upstream feature that just isn't working on
OpenBSD yet. That wasn't clear from the earlier mails.
That could be something which is reasonable to patch in ports.
Though for your use case, I think you'll be happier with performance
of something in-kernel. If vxlan doesn't
Socat upstream tells me that they don't have resource/time
to add tun/tap support on OpenBSD.
No matter anyway.
Thanks again

Hi, with vlanx(4):
In both endpoints I can set p-t-p mode with a destination UDP port,
but I can't set what is the source UDP port to bind to.
With static IP address I tested and it works fine:
# ifconfig vxlan0 tunnel :4789 vnetid 1
Anyway, if the REMOTE_IP is not static, I should destroy and

OpenBSD tun(4) devices always prepend the address family of the
received
Test:
OpenBSD UDP Server:
# ifconfig tun0 create
# ifconfig tun0 inet 192.168.74.1/24
# socat -d -d UDP-LISTEN:11443,reuseaddr GOPEN:/dev/tun0
2023/11/13 10:30:58 socat[31554] N listening on UDP LEN=16 AF=2
0.0.0.0:11443
2023/11/13 10:33:27 socat[31554] N accepting UDP connection from LEN=16
AF=2
I was thinking about using a more "point-to-point-oriented" method than
vxlan.
Anyway, I'll do some tests with it and let you know.
Thanks

I will do it.
Anyway, a few months ago I noticed a similar issue on vlc.
Prior 7.4, OpenBSD port didn't have the telnet interface available.
Some gentlemen here in ports@openbsd.org added it and now it's available in
7.4.
That is why I submitted the question related to socat and TUN.
Thanks

Have you
you would need to talk to socat upstream, because in general the ports
team do not add features

I would like to set a point to point interface encapsulating packets via
UDP.
It would be like a point to point wireguard but:
- without authentication (I can set permissions in PF on source ip)
- without encryption (content is already encrypted by source application)
