Hi,

Is iptables running on the machine?


Code:
iptables -L -n

If so, you'll need to write a rule to grant access - you might have OUTPUT rules.

You can quickly test if iptables is to blame by (temporarily) disabling it, and telnetting to the destination server on the appropriate port.

Cheers,
ZB

Without even little knowledge of your network infrastructure, I don't think it's possible to just hand out the solution.

Please let us know how your clients are connecting to the server. Is there any external firewall in between? Which port are you trying to open? When you say "site", do you mean "website"?

Check whether the port has been enabled through firewall.
