Re: [squid-users] tcp_outgoing_address problem/miss configuration

Does nobody have a tip for me ?!
I have tried diferent combinations of the http_access rules over the
weekend with no success.

All users that have access with th eir SRC-address are able ot use
every tcp_outgoing_address but they should be only alloewd to use
their specific configured one's.
Thanks.
