[Solved] Cisco VPN Client on Windows 7 breaks IPv6 tunnel

[jimb]

You where right!

I have deinstalled the Cisco VPN Client (version 5.0.07.0290) and now IPv6 works again.

Thanks for you help,
Adam

Next step:  Yell at Cisco.  :P

There may also be 3rd party VPN clients that will work with your VPN (and hopefully won't break IPv6).  May want to look into this: http://www.shrewsoft.com/home

Of course there may also be some option to set under Cisco VPN client to make it work too.
