Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm building a small proxy server with my 8 ip's that I have but, if I give 1 user access to more ips, no matter which one he uses as a proxy, the squid server will use the first one matching the rule.

As you can see from my squid config file, user manfred has access to all ips, but whatever ip I chose, squid only uses the first one in the list: x.213.223.188

Any idea how to force squid to use the required proxy for that user.?

Try something like:

acl user41 proxy_auth manfred
acl user41 myip x.213.223.188

acl user42 proxy_auth manfred
acl user42 myip x.213.223.189

and leave the tcp_outgoing_adress as is.

EDIT: ah yes, maybe instead something like

acl ip_1 myip x.213.223.188
tcp_outgoing_address x.213.223.188 ip_1

acl ip_2 myip x.213.223.189
tcp_outgoing_address x.213.223.189 ip_2

and leave the proxy_auth acls alone:

acl user_manfred proxy_auth manfred

Then

http_access allow user_manfred ip_1
http_access allow user_manfred ip_2

running squid -X on that gives me this: 2010/02/18 08:24:12| aclParseAclLine: ACL 'user41' already exists with different type. FATAL: Bungled squid.conf line 45: acl user41 myip x.213.223.188 Squid Cache (Version 2.6.STABLE18): Terminated abnormally. –  Ian R Feb 18 '10 at 14:25
