As a follow up on the Ubuntu linux VPN tutorial it is worth pointing out one more tip on getting this to work. With newer versions of vpnc, you might get this message when trying to initiate a vpn connection:

vpnc: no response from target

This is simple to fix simply by adding the following line to your vpnc.conf:

NAT Traversal Mode cisco-udp

So your /etc/vpnc/vpnc.conf file should look something like this:
IPSec gateway 217.32.131.20
IPSec ID General
IPSec secret aa@thattosuri22pr*7uv8pespfosic$
Xauth username clacy
NAT Traversal Mode cisco-udp

Thanks

Thanks a lot, you nearly saved my life. I was fumbling around with this Cisco VPN client which clearly was written 5 minutes after invention of electricity - just because vpnc refused to connect after an upgrade. There always has been trouble with the Cisco code because it simply is too old, but it seemed to be the only way that worked. Now I can go on with vpnc again. Thanks, my hero!

Thanks!

Just wanted to say thanks! this and your previous post (as well as this forum http://ubuntuforums.org/showthread.php?p=5957882) helped me get this working on my lil asus eee.

Just so you know this method is still valid in intrepid ibex and as far as I can see there is no native support (if I'm wrong I couldn't find it)

Thanks alot - this saved me after 5 hours to get it all working as I thought it should only to recieve "no response" nearly killed me.

Thanks a lot! Worked like a charm... Another important thing is to use the IP for IPSec gateway address, not the name! But your hint saved probably hours of my lifetime! Thanks!
