SOCKS proxy directly to ISP?

[verulian]

I have a scenario where I'd like to do something similar to this. The idea is to provide the entire network with several VPN connections over a fast ISP.

However, there are times when I need direct ISP access and I want to provide a SOCKS server port to allow this so that direct ISP access is the except vs the general rule.

Can this be done with OPNsense and are there some instructions or examples that demonstrate?
