i am new in linux networking and apache server configuration.

someone gave me two linux server under same vpn. Redhat is installed on them.

those server has both internal ip and external ip. i mean external ip are forwarded to those internal ips.

i have installed apache on those server and also uploaded php websites on them. so i can access website installed on those server from internet(from outside of the vpn) using their external ip.

both server has hostname(i mean i get a local domain name by the hostname command)

and also from ssh i can ping one another by both external ip and internal ip and that hostname.

but from the php end of the installed website i can't access the website of one server from another server.

i have tried with file_get_contents and curl to access websites. i have tried with both external ip and internal ip and hostname but all fail.

i checked the both file_get_contents and curl and found those are working with other public websites like google dot com etc.

but its not working only when i am trying access from one server to another on that vpn(i mean same network)

can you please tell me what is the problem?

is it apache configuration problem or vpn setup or ip forwarding problem?

please help.

Regards Al Amin
