Isn’t PPTP heavily deprecated, or is that just when used with certain encryption methods?
It may be, I don't know for sure. However, while it is still in IPFire I think it is better to have the latest version from 2018 rather than the one from 2008.
Yes, in terms of bugs in the implementation it is.
PPTP is a universal tunnelling protocol (short for point-to-point tunneling protocol) and it can be used for VPNs. However it is very old and the specified cryptography is very outdated. In IPFire we only use it to connect to some DSL providers which use it on the Internet link. They do not use any encryption and use weak authentication to identify the subscriber.
