Need some VPN help

[cannon_dt]

Hi,

I used the vpn portion of the guide over at http://digitalstudio7.blogspot.in/20...-in-other.html. However after successful establishment of the vpn connection, it drops off in a matter of seconds rendering it dead. Below is the snapshot of my syslog, can someone please help

Thanks,
Ananth
