Configured mailman but can't browse to index page from a different machine

Question

Hi, I configured mail man on a server and it says got to page

http://server1/mailman/

It works locally on the server; but can access that page from a different machine; it fails;

-> I am using Cent OS 6 and mailman -> Do i need to open any http access ports? I though outgoing port 80 is open by default.

Please do let me know if any questions.

Answer 1

Found out its a firewall issue, stopping IPtables fixed it.
