Opened Ports for Inbound and Outbound Traffic (Windows SharePoint Services 2.0)

In this server farm, certain servers need access to the Internet to send e-mail and resolve DNS addresses (the SMTP and DNS server) and respond to User Datagram Protocol (UDP) and HTTP requests (the front-end Web servers). Inbound traffic requests to the Front End network go through only Port 80 and port 443, and these ports need to be open.

Port 8080 is the port configured for Windows SharePoint Services server farm administration and synchronization. Port 8080 traffic is only allowed for internal communication and synchronization across the Front End network. Port TS 3389 is open on internal front end and back end servers but disabled on the Internet router and BIG-IP controllers. The Internet Platform and Operations group accomplished server management by using a Terminal Services session that goes through one server in the edge network before connecting to the server farm to help provide a high level of security.
