Configuring Draytek Modem for Port Redirection for SBS 2008 or SBS 2011

Filed under: Draytek, SBS — Tags: , , , , — solutionsthroughit @ 16:05

The following ports need to be opened and forwarded to the server for an SBS server to be able to function on the internet.

  • HTTP (80) – will answer & redirect to HTTPS for a better user experience
  • HTTPS (443) – is the primary transport for Outlook Anywhere/Outlook Web Access
  • VPN (1723) – Optional.  This will allow users to create a VPN connection to the SBS server, and is therefore controlled by VPN access defined per user or group.  NOTE: VPN access should only EVER be granted to computers (and associated networks) where you are SURE that they do not have any security risks.  You are effectively plugging the VPN’ users computer (and depending on how it is setup, their network as well) to your business network.  Not always safe!
  • SMTP (25) – Allows the server to receive email in from the internet.
  • RWW (987) – Allows users to connect to their PC or Terminal servers, without the need for a VPN connection, ensuring that any network transmittable ‘bugs’ that are on their home computer, don’t make it into the office.
