proxyproxy (snap name “proxyproxy” by publisher “unprofessional”) is a tool that runs locally and serves as a http/https proxy. It monitors networks connections and reroutes your traffic directly to the requested endpoint or a corporate proxy depending on the network/subnet the machine is attached to. It’s purpose is to facilitate the handling of various corporate proxy configurations.
In order to work as expected with confinement: strict the following plugs must be auto-connected:
network
network-bind
network-observe
network-observe is not auto-connected by default and is therefor requested.
Having taken a quick look at the source I am for granting auto-connect to network-observe. However, I also noticed the app has the following path for configuration: /etc/proxyproxy/config.yaml, does your snap accommodate that?
