Not sure if I am reading it correctly. But what ip adress is your given to your pc?
It reads to me like you have router 1 and 2 on router 1’s network but your pc is on router 2’s “internal” network… which must not be in the same 192.168.1.x range as is router 1’s network.
Put router 1 under 192.168.2.x range Then Then Router 2 with 192.168.1.x adressing should work still, and the pc should be able to talk to the router-1 network.
This is expensive cgi, it screams it. Not quite sure why they made it but someone needs to be convinced of something for sure.
(Just compare it to any footage of SpaceX landings, this video is far to clean, the sky alone is “perfect”)
