Firewall blocks PHP sockets

[Guest]

Hi all.

I have newly installed Endian Community Firewall 3.3.18 and set our VPSs behind it; two of which are a Centos 7 server and a Windows server. Both serve some websites and APIs. After installing and configuring the firewall; both servers can not reach each other through HTTP. Web sites work very well on the browser; there is no port problem.

I open an RDP to the Windows VPS, I open the browser and browse the API URL successfully. But the very same server times out when I try to reach that URL with PHP (cURL or PHP Socket (file_get_contents()). THe same case applies from Centos to Windows too. I open Centos terminal, ping the API URL in Windows server, it is successful. On the very same terminal I try to connect with cURL, but it times out too.

This has become a very immediate problem to us.

What are we missing in configuration of Endian?

Had resolved the issue temporarily by defining local IPs with domains in their respectful hosts files. But how to set NAT loopback in Endian for good?
