Windows RDP is what I need to use, but I also need a lightweight web bastion. Guacamole works, but is too heavy for the kind of proxy/router/equipment I’m targeting.

Ah, I understand. Do you need GUI for that router stuff can’t just use SSH? What about xtightvnc with novnc web fronted?

No, I need to access legacy applications that have no web versions. You do realize that there is more to computers than the Internet and web development? :)

Man I was playin with computers before the internet, so...I guess I do. Do you? Hahaha! :) You know if you use novnc from the web you can connect to a non web application, right? Your use case is not elucidated very cleary. Maybe you can try....being more clear? Hahaha! :)
