Those both require dedicated IP on both ends of the connection, which is not
always the case on residential ISPs' IPv4 now.

I'd suggest to check out L2TP instead, which doesn't, and can be used without
encryption too, that one can work.

Or PPTP as mentioned, but it's more complex (separate signaling and data
protocols) for no good reason and has more issues traversing NATs/firewalls.
