Hi, I have a Squid server used on a test network. I want to allow some users to authenticate through the proxy if they are on specific IP addresses, to test software functionality, using basic authentication. However, the rest of the clients should go through without authentication. I have ACLS such as: Acl Authenticated_IPs src 10.10.10.50 10.10.10.51 proxy_auth REQUIRED Acl Test_Network src 10.10.10.0/24 10.10.30.0/24 http_access allow Authenticated_IPs http_access allow Test_Network This obviously doesnt work because the proxy_auth REQUIRED bit at the end of the first ACL is not understood by the SRC part. So is there any other way to get a similar configuration working? Thanks. Andrew. -- allpay.net Limited, Fortis et Fides, Whitestone Business Park, Whitestone, Hereford, HR1 3SE.
