Microsoft SharePoint 3.0 – (Part 1) Alternate Access Mappings

This is just a simple note for Microsoft SharePoint 3.0.
This article is concerned the feature – Alternate Access Mappings, which is necessary for people to connect to the site from internet/extranet.
The Alternate Access Mappings is used to isolate the site from being connected by unauthorized zone. If the connection from that zone is necessary, Alternate Access Mappings must be configured so that the site can be connected.

Originally, if one site is built, we can see the result at Central Administration -> Operations -> Alternate Access Mappings, in following

Internal URL Zone Public URL for Zone
http://hostname Default http://hostname
http://hostname:port1 Default http://hostname:port1
http://hostname:port2 Default http://hostname:port2

however, in this configuration, the internet user is not accessable. So, we need to add another mapping to this mappings,

Internal URL Zone Public URL for Zone
http://hostname Default http://hostname
http://real-ip Extranet http://real-ip
http://hostname:port1 Default http://hostname:port1
http://real-ip:port1 Extranet http://real-ip:port1
http://hostname:port2 Default http://hostname:port2
http://real-ip:port2 Extranet http://real-ip:port2

With the extranet mappings, the insternet user can now access the resource via typing the real-ip, ex: http://real-ip will connect to Default Web Site(80).

To configure this mappings, go to
Alternate Access Mappings,

1. Edit Public Zone URLs
2. Choose the site from the Alternate Access Mapping Collection which you want to map
3. Type the real-ip address and the same port number on the “Extranet” field, then save it.


Note : this configuration does not need to configure IIS. You need to keep IIS in original configuration. The Site -> IP Address field should be (All Unassigned).
