<div class="content wysiwyg-content">
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. &nbsp;In the router, I have to fill in the following fields to open the ports: Application Name, External Port, Internal Port, Protocol &amp;&nbsp;IP of the server.<br />
<br />
The router automatically takes care of the entries for 80 and 25.<br />
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. &nbsp;With regard to Protocol, I suppose it can be set to both for all. &nbsp;The router help file just says &quot;Check with the Internet application documentation for more information&quot;.<br />
<br />
Can you please help to complete the table?

Opening Ports on Linksys Router WRT300N

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
