Greetings.. maybe you can help me. This is something really strange so I thought I would ask for help. I searched the forums and couldn't find any other post like mine.
Centos 5 64bit
Zimbra Version 4.5.6_GA_1044.RHEL5_64 Jul 10, 2007
Network Version Trial
The Admin Web Console works fine from outside the local subnet but Web Based e-mail does not. If I point a browser on a workstation on the same subnet as the server, to the address: http://220.127.116.11 it comes right up and requests a login. If I try to do the same on other subnets, it does not work. The page times out with a "connection refused" error in the browser.
Telnet to 18.104.22.168 port 25 from any other subnet works fine
Telnet to 22.214.171.124 port 110 from any other subnet works fine
Accessing the Management console on any other subnet works fine
Webmail does not
I can access WEBMIN (web-based admin tool for Linux) from the other subnets no problem as well as ping the box from any of the other subnets. So I know it's not a lan/routing/ip issue.
Also, because of this problem, SELINUX and IPTABLES are both disabled
Of course I tried rebooting as well.
Reason for the Need:
Several branch locations are connected via VPN Bridges (fixed VPN connections). All need access to the server both for POP3/SMTP & Webmail.
Any help would be greatly appreciated
