port forwarding

   I don't know what that means.  What, exactly, are you trying to do?

   You first?  What, exactly, are you trying to do?

   "reach" _how_?

   "not able" is not a useful problem description.  It does not say
what you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   Unrelated to "reach my pc".

   Are you running a web server (on your "my pc")?  There's no reason to
hide that IP address.  (What about port 443?)
