Crisco VPN doesn work anly longer

Hallo,

I ve no idea what is going wrong. Perhaps a missconfiguration beacause I changed some rules but nothing affecting VPN.
The VPN worked for month before without any problems.

Here are the lines with error-messages out of the livelog.

Thanks for any hints.

Rald
