Exchange 2010 port 6001, 6002 and 6004

Hi there,
Is it safe to open up the ports 6001, 6002 and 6004 on my main firewall for exchange 2010?
Thanks

Safe? I guess so, but you don't need to. They are internal ports used by Outlook Anywhere. Outlook Anywhere is designed to run over port 443 only, then the RPC Proxy makes the connections to those ports on the required Exchange servers.

No need to open those ports to the internet.

Simon.
