Yes, I see the "connect success but no packets get through" a lot and lots 
of users in my university see the same when using vpnc.  Using Windows 
noone has this problem so it is vpnc specific.  I like your admin told 
you, assumed it was to do with the fact that vpnc just closes the tcp 
connection (in the case of udp it just stops sending packets) and doesn't 
actually close the vpn connection to the server.

I never got a reply from anyone about this when I posted to this list.  
)-:  Hopefully you have better luck...

Interesting.  I will have to try that and see if it works here, too.  If 
necessary we could automate the procedure to always do a login with a 
wrong password and immediately to try and login again with the right one.  
The vpnc-connect script could probably do that...

Thanks for the hint!

Best regards,
