Unfortunately, it was later discovered that PPTP aliasing does not work when more than one internal client connects to the same external server at the same time, because PPTP requires a single TCP control connection to be established between any two IP addresses. Hopefully, this will be fixed in the future. This is documented in 5.0-CURRENT's libalias(3) manual page.
