Some people are reporting success with two-hop proxies, since not all
networks in Iran are subject to the same blocking rules. The first hop
is to another host in Iran that is less censored; the second hop crosses
the border. I haven't seen a report of someone doing this with
onobfuscated WireGuard specifically, but it may work. The second link in
the list has a kcptun component, which is UDP.
