  • FireWall port for RCP over https

    I configured my Webmail (Exchange 2003) as proxy rpc
    I have tested https://mywebmail/rpc/rpcproxy.dll with success.
    But I have a stupid question:
    On my firewall (From outside to inside) do I have to open port 443.
    And It doesn't work !
    Do I have to open the 80 also ??
    Thank you !

    I have an equally stupid question :
    Is 443 being forwarded to your Exchange server?

      You must allow only port 443 through your firewall, because Outlook requests use HTTP over SSL. If you already use Outlook Web Access with SSL or Exchange ActiveSync with SSL, you do not have to open any additional ports from the Internet.

          Thank you.
          I was sure about the "443". But in some doc. I see that we have to open the 443 and 80 !
