I need VPN to get into some internal resources via SSH, but there are lots of external/public/AWS resources I also need to access, and the full VPN adds too much overhead and fragility for those.
Using the available split VPN, I can point a browser instance at a localhost SOCKS proxy port to relay over SSH + VPN for other web resources I need to access internally.
Unfortunately, Firefox proxy config rules are sort of backwards for my needs. I want to say "only use proxy for these 3 domains" whereas it wants to use the proxy by default and only allow me to bypass specific domains.
