Unsure about Proxy scenario

[fbeye]

Hi so on my Opnsense I do have WG setup and works fine but the problem I have is, from work, I can not access anything that is not already on the laptop, I do not have admin rights... I was wondering, is there a way to set up a Proxy on Opnsense that connects to my LAN , and at work, on existing Firefox connect to that Proxy and then go to "lan" ips via firefox [web based stuff].
