Hi,

How do we check or where i can see the list of blocked IPs?

Our FreePBX is installed in our main office, and our second office using the same server by using the Public IP of the server. But now were having a problem, our second office cannot connect or access the server anymore, but i can able to access the server from home and from our main office. I can also able to access from my friends house, only our second office cannot access the server.

Need your help.

Thanks!

Check whatever firewall you are using as to allow networks and hosts.
