but It forbid me access to one site 'mysite' even if I soped the proxy & proxyguard
even more It forbid access even if deleting the packages squid & squidGuard.

In the rules I Allowed all.
Thanks for help.

here is a message from firewall :
500 Internal Privoxy Error

Privoxy encountered an error while processing your request:

Could not load template file connect-failed or one of its included components.

Please contact your proxy administrator.

If you are the proxy administrator, please put the required file(s)in the (confdir)/templates directory. The location of the (confdir) directory is specified in the main Privoxy config file. (It's typically the Privoxy install directory)

"address Range I used in OpenVPN <=> public ip of webserver"

How would that be??  You assigned public address space to your vpnclients?
