Cisco VPN Client and UMTS on Windows 7

Is this a problem that occurs immediately, or does it work for a few minutes and then die?

The problem occurs immediately and the connection is up as long as i close it manually.

Ok. I use the same laptop with UMTS internal card, and there is an issue with the Dell driver. It has a network card emulation built in, with a DHCP server functionality that has a lease time of only 5 minutes. This lease is of course expanded every time, but unfortunately Windows (XP in my case) is resetting all kinds of network uses whenever this occurs.

We use VPN via PPTP, and it is lost when this occurs.

Workaround: don't use the Dell drivers, but use drivers from Ericsson. I have asked Dell about this problem but they did not respond.

But when you cannot get it to work at all, you probably have a different issue.

Thank you,

i´ll test a different driver first. I also read about problems, with private ip-ranges like 10.x.x.x (that i get from my provider), but the vpn-client works with win-xp.

Hi Marco,

you should try with the transparent tunneling set to IPsec over TCP and configure the VPN gateway accordingly. It's not unusual that providers don't support NAT-T IPsec over udp/4500. It's worth to to give it a shot.

Hi Uli,

i´ll try to reconfigure the gateway for this test, but i wonder why the connection works fine on win-xp.

Thanks for your help!

Hello,

i found the reason for this problem. The cisco vpn client does not support WWAN devices on Windows 7.

It´s described here:

I guess i have to wait for a new client-version, that supports this feature.

Have you tried the shrew.net client?
