[pptp-server] PPTP and NAT?

[Patrick Reid]

There is another option:

Install the PPTP client on a Linux gateway/firewall; have it establish a VPN
connection with appropriate routing; the customer can then just use the
Linux box as the gateway.

Stefan:

Can you tell me more about your first option?  I'm using a linux firewall
(2.2.16 Kernel with masquerading/firewalling rules), but I don't see how
patching my firewall will fix the GRE routing problem at the remote site.
The
packets from the different remote clients will still come in with the same
IP
address, right?

Your second option works, but doesn't scale very well. When my remote
customer
gets up to wanting 10 or 20 clients, I'm in big trouble! :-)

As for the third option, where can I read more about it?  I've never even
heard
of 'PNS'.
