Site for IP will not go

[tomazini]

Dear, I'm new to PFSense, my proxy is transparent with SquidGuard. I'm having the following problem. All sites call some IP address. Do not work! For example the customer enters a support chat site. This Chat behind calls some address that uses only IP. When it is so the browser does not address. But on my firewall I did not define any kind of blockage. Would anyone have any tips?

When I put Bypass Proxy for these Source IPs. I can make it work on the computer. I do not know how to solve it.
