Hello Squid Support, We upgraded our Squid Web Proxy from 2.5 to 5.5 recently. After working out a few issues with backend services and authentication, our client can finally browse the web and adhere to all of the ACL rules and lists as expected.
The problem we’re having now is that we’re unable to access local resources on different subnets. For instance, our “main” networks are 10.46.x.x and 10.47.x.x, but the proxy is blocking us when we try to get to 172.26.x.x as well as 10.96.x.x.
When comparing our current config to the old, they are very nearly identical, and the old config works with no issue. Is there some change from 2.5 -> 5.5 that would stop some of our allow/deny rules from working as expected? Or maybe I need to open up the
ACL’s a bit more or define those subnets explicitly now? I can post our config below, I’ll skip the sections that most likely don’t pertain to the issue.
