TCP 25 - inbound SMTP mail delivery TCP 443 - inbound HTTPS for OWA TCP/UDP 53 - if you host your own DNS
If you want Outlook, use a VPN. The PIX will do IPSEC based VPNs and you can use the Windows 2000 or Windows 2003 IAS (RADIUS) service to authenticate against the AD. Or you can just do PPTP VPNs to the RRAS service on Windows 2000. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Justin Lape Sent: Thursday, September 18, 2003 9:51 PM To: Exchange Discussions Subject: Exchange 2000 Firewall Ports Windows 2000 Server Exchange 2000 Server I recently got a Cisco PIX and I need to know what ports are absolutely necessary to allow inbound traffic through the firewall for people to be able to send mail in, access OWA, etc. I am reading that port 135 needs to be allowed inbound but due to all the hype with RPC these days I was wondering if the port was necessary. Thanks in advance.
