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) I can't use GIF or GRE interfaces because I'm behind NAT with only TCP/UDP capabilities. With linux it's possible with fou-gue interfaces, but I see that in OpenBSD fou is not implemented. So, I installed socat with pkg_add and tried to do like this: http://www.dest-unreach.org/socat/doc/socat-tun.html Anyway, I see this: # socat UDP:1.2.3.4:11443 TUN:192.168.255.2/24,up 2023/11/11 14:11:27 socat[4504] E unknown device/address "TUN" Do you think it's possible to add TUN/TAP support in socat?
