- Only web interface (protected by sign-on) should be available on external
interfaces.
- Proxies should only be available on internal interfaces. Otherwise, they will
become open proxies on the Internet which might have implications for the
FreedomBox user.
- Update description to convey that we are not opening SOCKS proxy but only
HTTP, HTTPS and IRC proxies.
