PPTP has a reputation for being insecure. Could you configure IPSec instead?
When I last tried it, the best IPSec implementation for Linux, in my
opinion, was StrongSWAN. However, I don't know how well it works with
Windows clients. You should be able to find sample configurations on the
StrongSWAN wiki and via your preferred Web search engine.
If you don't mind installing software on the clients, you could try OpenVPN.
I haven't used it, but it has a good reputation.
