Home user cannot connect to Cisco VPN

Hi, I have a home user who cannot get a connection to Cisco VPN Client.  I'm using version 5.0.02, and there are two different IP addresses/routers/sites that it won't connect to, so it seems to me it must be something on her computer or her router blocking it?  When trying to connect to a client, I get the message "Secure VPN terminated locally by client.  Reason 412:  Remote peer no longer responding."
She has a Linksys router.  Is there something I need to change in her router or on her computer?  Let me know if you need any further information/clarification.

Thanks!

Can she not connect to any VPN's or only some?

Wondering if you need to select the VPN pass through on the Linksys.

I've seen that before. I think all I did was reload the client.

Probably it doesn't support a VPN passthrough (you can enable it in the Linksys configuration - security tab).

Which one do I enable on the security tab?  Here's where they're set at:
Block anonymous internet requests - enabled
Filter multilcast - disabled
filter inernet NAT redirection - disabled
Filter IDENT (port 113) - enabled.

There are 2 different sites she's trying to connect with the cisco client VPN and cannot get to either.  However, she also uses a Netgear SSL VPN to connect to our office and is able to do that.  It's just the Cisco Client.

It could be an unstable client internet connection or MTU issue as well.
Please check your MTU size (try with 1300 or the smallest possible) - application is located in the same plasce where you have you Cisco client.

The problem could be 1 of 3 things.

1 - The Cisco kit she is trying to connect to doesn't have NAT TRAVERSAL enabled.
2 - The local XP/Vista firewall doesn't have the VPN client dialer executable (VPDIALER.EXE i think) listed as an exception
3 - The local and remote subnets are the same.

MTU size is at 1300, smallest possible is 576.  I can change it to that and see what happens (but will need to reboot), but additional info I neglected to give you (sorry) is I installed the Cisco VPN client here in the office and tested it with an internet connection outside of our network and it worked fine.  It wasn't until she brought her computer home that it wouldn't work, which is what leads me to believe it is something in her Linksys.  Her local IP is 192.168.1.1.  Does that help?

IanTMCommented:
It only helps if we know your subnet in the office.

Because she is behind a Linksys (effectively a Cisco product) my money is on NAT TRAVERSAL.

I'll check to see if we have NAT TRAVERSAL enabled, but what is the likelihood that 2 totally separate entities would not have it enabled?

lpelletier_ncssAuthor Commented:
Our subnet is not the same as her's.

IanTMCommented:
NAT TRAVERSAL is enable on the destination router/pix not at the remote site.

This is required to enable the router/pix to understand IPSEC packets encapsulated in a NAT'd IP packet.

This is one person with a client problem right?
Have you tried uninstalling and reinstalling? I used to administor 1500 VPN clients that connected to my ASA5520 and if one person would randomly pop up with a 412, I uninstalled and reinstalled (most likely an issue with the Deterministic Network driver)  and everything popped up and worked.

lpelletier_ncssAuthor Commented:
We are one of the destination sites she's trying to get to.  I'm going to try reinstalling Cisco and will let you know.

lpelletier_ncssAuthor Commented:
Sorry, should have tried this first, as you were the first one who responded with trying to reinstall, which I finally did, and all is working fine now.  Thank you!

Thanks everyone, reinstalling worked.
