[squid-users] Unable to access internal resources via hostname

[Piana, Josh]

Antony, 

So those two rules were definitely not the way to go, thank you to those who clarified that to me. 

I'll remove them. 

This is really frustrating. I've been trying to get a working Squid configuration for weeks now and it is literally a 5 minute process for most people. 

I'll keep looking and see what else could be blocking traffic.

No; firstly the "localnet" ACL is defined by *source* address, therefore "localnet" matches traffic *from* your local network.

Secondly the ! negates this, therefore "!localnet" matches any source address which is *not* in your local network.

Therefore "http_access deny !localnet" denies any access from an address not in your local network.

This then allows access from any address which *is* in your local network.

Now, having matched all traffic not from your local network, and all traffic which is from your local network, you have accounted for all possible traffic, therefore any other rules have no effect.


Hope this helps,


Antony.
