Squid - transparent proxy does not work after midnight

[user1378]

hi every1,

i am using squid 2.7.9 on pfsense 2.1. works fine. i enabled the transparent proxy mode. works fine!

but after midnight (my internet connection gets reset at 0.00) the transparent proxy feature doesn't work anymore.

system logs says:

after i hit the save button on the proxy server config page the transparent proxy works again and the system logs say:

Mar 27 07:16:57 php: /pkg_edit.php: Reloading Squid for configuration sync
Mar 27 07:16:57 check_reload_status: Reloading filter
Mar 27 07:16:57 check_reload_status: Syncing firewall
Mar 27 07:16:58 php: /pkg_edit.php: Reloading Squid for configuration sync

telling IE the proxyserver and port works all the time.

so it seems that squid looses the filter configuration after midnight (as the systemlogs say). but why is that happening and how can i fix this. reinstalling the squid package didn't solve the problem :-(

any ideas??
i appreciate any help.

you can work around this situation by installing cron package and calling squid_reconfigure() php package function to force new ip on squid config file.

how do i call squid_reconfigure().php through cron?
i didn't find any files:

find / -name "*squid*.php"

searching for proxy only gives me these files:
/usr/local/www/services_igmpproxy_edit.php
/usr/local/www/services_igmpproxy.php
