PfSense connect through proxy

[ip25mac]

Hi everyone! I am new to pfSense. Receiving service from a proxy, I have a setup like the following:

proxy–---> Pfsense------> Users

My problem is that I can ping but I can not browse or download packages. I get the following error, "Unable to communicate to pfSense.com. Please check DNS, default gateway, etc." Could someone tell me if this can be done? If so, what would the correct settings? Of course, thank you very much.

Go to system -> advanced -> miscellaneous

and set up proxy support
