pptp passthrough error SOHO91

Unanswered Question


i would like to connect to a Microsoft RAS/VPN server using my laptop (winxp).

my laptop is behind a cisco soho 91 router which is located at my home. i use the built in vpn client in winxp with pptp protocol.

i got the 721 error every time i try to connect to the server. The SOHO 91 runs the newest firmware.

the whole process stuck in the verifying username and password phase.

if i try to same using a cisco 1750 as the remote router, everything is working fine.

i did a seach of this and i see many people have already faced this problem but i didn't find any solution.

any help would be nice

I have this problem too.

Try these workarounds

Define the static mapping for the inside interface to outside

Configure and apply the ACL to permit the GRE return traffic from the PPTP server to the PPTP client.

Apply the ACL to the outside interface.
