[FR] How can I expose the wireguard tunnel as a socks5 proxy on the client?

[Chris]

Maybe I oversimplify your problem, but from what I read, your standard route 
will be using the Iranian net.
And - I guess - it is only a limited numer of IP addresses, that you would like 
to reach through the tunnel.

I don't know your OS, but simply adding ip routes pointing to the tunnel for the 
desired destinations would do the job.
