I updated a Soekris 4801 from b11 to b14 yesterday.  The site to site tunnel
that was setup disappeared.  I checked the backup XML file and the tunnel
was in it. So I restored the backup config file still no luck, then I tried
a backup from a few weeks back, same result.  Once I rebuilt it manually
everything was fine.  Any ideas why it did not survive the update?  My
personal 4801 which has a few tunnels updated from b13 to b14 with no
problems.
