VPN connects but no ping/rdc into network.

Hello jpaulo_almeida,

What version of the VPN client are you using?

Regards,

Cisco  VPN Client, 5.0.00.0340

That is a vista compatible release but a very early version (5.0.00.0320 was a beta). I have seen 5.0.01.0600 so I would suggest upgrading just incase there is an unsupported feature or bug in your version.

Tried upgrading VPN Client (5.0.01.0600), but no sucess to the problem.
uninstall & install worked fine.
IPSec/TCP is OK but IPSec/Udp is not. Same problem.
here is a ipconfig /all (wireless adapter is disabled now) :

Any ideias ?
thanks,

Sorry I dont have any furthur ideas. Someone like lrmoore might have a better idea.

Please,
Any ideas ??
I'm sure this is a problem with my Vista installation, because in XP it works fine.
Thanks in advance.

Have you tried email lrmoore and asking him to take a look. His email address is in his profile.

I have the same problem in regards to my DNS servers.  It's happening on two different Vista computers to many different routers.  I am running
5.0.02.0090 on one, and 5.0.03.0530 on the other.
both of them experience the same problem.
Other than the bogus DNS, everything is working fine.  It's not the Cisco Router because other computers can connect fine.
I've reinstalled many times.  Now even older versions are giving the same result on the same computers.
The DNS i get assigned is
fec0:0:0:ffff::1%1
fec0:0:0:ffff::2%1
fec0:0:0:ffff::3%1

Does anyone know what has happened here?  i can't find much on the net.

I know this is a bit old, but I'm experiencing the exact same issue. The DNS appears due to ISATAP implementation in Vista for ipv6, I believe. My XP VPN clients (Cisco IPSec/UDP) connect and access resources fine, but my Vista clients are hit-and-miss. Every time I ipconfig/all and compare it to a working Vista connection, the DNS is the main difference.

For us, we have a 515 handing out the regular ipv4 DNS addresses for our DC's, but this is somehow translated by Vista's ipv6 stack? Some info I'm reading says that this is perfectly normal, and others say that ISATAP (or the MS implementation) is a poor 'piggyback' hack to get ipv6 testing on ipv4 networks. Obviously, I'll try disabling the ipv6 option on the interface and post the results.

Hello,
My solution :
Get Cisco VPN client 5.0.02.0090 or later
Get latest Deterministic Network Enhancer update (from their site)
(without any VPN client installed on your Vista)
1. Install the downloaded Deterministic Network Enhancer Update. Reboot.
2. Install Cisco VPN client 5.0.02.0090 or later
3.Deactivate the IPv6 protocol for each network adapter. On the properties tab simply uncheck IPv6.
Then select Sharing Tab and uncheck the box "Allow other network users to connect through this computer's Internet connection". Save and repeat for each network adapter.
4.Start the command line prompt as administrator and enter following line:
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 1 /f
5. Reboot
Notes : This was copied from a web page (don´t have the link anymore). Works most of the time. Sometimes a reboot helps if your getting "Falied to enable network adapter".
It also helps to disable other ethernet interfaces like wi-fi or other.
This is my experience. I have about 6 connections working in my laptop to diferent locations.

After a while i found the link i used :
