Question

What ports should be open for Exchange Server 2007?

Asked by: nielsenfinancial

I am running a single box exchange server (w/o edge transport server) behind a linux server that is acting as a firewall for my network.  What ports do I need to open for exchange server 2007?  I would like to use OWA, POPssl, IMAPssl and outlook anywhere.  The active directory and dns is located on the same server as exchange.

I have these already open, but I was wondering if I needed the LDAP ports open in my situation. I have read about ports 389,636,379,390,3268, and 3269. And then for protocol x.400 port 102. I have read in one spot that outlook anywhere only uses 443, so do I still need 135 open for rpc?

Hi, No only open what ports are essential. You use your Linux Box as a firewall between your Windows Network and the Internet therefore you only need to allow the ports above.
