give several ips to the pptp-server and let each client connect to it's
"own" server. (different server ip per client)

its so simple :-)

Betreff: [pptp-server] multiple clients from the same ip


it some days i got this problem, and i think there is no easy way to solve

I have a VPN poptop pptp server which listen on a refistered ip address.
Everything works fine; i can connect from a windows 9x/NT/2000/XP client
without any problem.

My problems start when more than one client connect to the vpn server from
the SAME ip; the gre protocol i think get lost and from two or more clients
it doesn't work.

I read in the mailing-list archive that poptop "respect" the rfc and it
cannot create more than one tunnel from the same ip.

Are there some new solutions continuing using poptop? If i put, on the
client side, a pptp-linux-client which acts as a router for the windows
client to the vpn server, do you think it should work?

Thank you in advance for your kind interest, hoping hear from you soon!
