Hello,
I have a very strange problem that only appears between two Cisco routers. The connection between the PPTP-client and PPTP-server hangs at the verification of username and password and returns Error code 721 (Remote PPP peer is not responding). The link between the client and server looks like this:
PPTP-client – Cisco(1) – Internet – Cisco(2) – PPTP-server
PPTP-client = Windows XP Service Pack 2
PPTP-server = Windows 2000 Service Pack 4 (running RRAS)
And now over to remarkable things:
If I change the PPTP-client from Windows XP SP2 to Windows 2000 SP4 it working.
If I change Cisco(1) to a netgear router it working.
If I change Cisco(2) to a netgear router it working.
The PPTP-client can (without any problems) connection to other PPTP-servers on the Internet.
A PPTP-client from the Internet can (without any problems) connect to the PPTP-server.
Cisco(1) = Cisco Router 1812
Cisco(2) = Cisco Router 871
Med vänlig hälsning/Kindest Regards
