Cisco VPN Client Problem

[pete8]

I've a Cisco Pix506e and configured VPN to allow remote users to connect. It seems to work fine for some users (with or without a router), however some cannot login from home or remote office.

Please point to me the right direction. Is it my Cisco configuration? Or the remote router?

check that they have vpn passthrough enabled on their home routers. also you try lowering the mtu settings in the client. could be dropping larger packet sizes.

Another thing to check is the ISP that the users that are having a problem against the ones that are not.

I have come across some ISPs on free pay-as-you-go accounts blocking IPSec or not having clear pass-through enabled(like freeserve etc). Try and use the same ISP for all your dial-up users once you find one that works.

I had the same problem on broadband even with the same ISP in different areas of the country. The problem is that when you ask the ISP support desk if they support VPN traffic they always say that "they do not support it directly" and do not guarantee it unless you use one of ther premium services.

VPN passthrough is not an issue, it's enabled on the Routers.

One particular user I visited could connect to other VPNs using Microsoft XP client (PPTP/L2TP). Cisco client does not seem to work however ...

Could that client connect to the vpn you are trying to access with the cisco client using the microsoft client?

or is that vpn unaccessable using both clients?
