I have created a Guest WiFi for my IoT things by following standard procedure outlined here: https://oldwiki.archive.openwrt.org/doc/recipes/guest-wlan-webinterface
It works fine and my dodgy Chinese stuff is not allowed to be near my internal network. I have one Raspberry Pi currently on Guest WiFi (192.168.3.100) that I would like to SSH to from my Home computer (192.168.0.100).
Basically, I want to route port 22 between Rpi@192.168.3.100 on Guest WiFi and firstname.lastname@example.org on my Home WiFi. Client isolation is turned on (if that makes any difference).
Is there anyone who can give me a hint on how to do this?
