Opening Ports on Linksys Router WRT300N
Posted on 2009-02-15
My SBS 2008 gives me an error that the following ports are not open: 80 HTTP, 443 HTTPS, 987 SharePoint, 25 SMPT and 1723 VPN. In the router, I have to fill in the following fields to open the ports: Application Name, External Port, Internal Port, Protocol & IP of the server.
The router automatically takes care of the entries for 80 and 25.
I don't understand if these listed ports are the Internal or External ports and I don't know how to find the opposite port for each. With regard to Protocol, I suppose it can be set to both for all. The router help file just says "Check with the Internet application documentation for more information".
Can you please help to complete the table?
