Sametime 7.5 Reverse Proxy configuration
In the Sametime Administrator's Guide, Configuring Ports and Network Connectivity (chapter 5), the
feature to enable reverse proxy discovery on the client is not functional. This feature enables clients to
connect to a Sametime server through a reverse proxy server. Corporate intranet users who are not
required to route connections through the reverse proxy can still establish connections with the Sametime
server.
Capability to enable reverse proxy discovery on the client enhances the existing logic in Sametime clients
by adding the reverse proxy connection logic to existing logic which is still present and operable in the
client. The Sametime Connect for browsers client includes a "Host name" and "Port" setting in the
Options-Preferences-Sametime Connectivity tab. The values in these settings are ignored when the
Sametime server is configured to operate with a reverse proxy server. (In a normal Sametime
deployment, these settings specify the Host name of the Sametime server to which the client should
connect and the port number on which the Sametime server listens for connections from Sametime
Connect clients).

Configuring Sametime to work behind WebSEAL reverse proxy
The administrator's guide contains a "Using reverse proxy or portal servers with the Sametime server"
that discusses using Sametime with reverse proxy servers.
If you are deploying Sametime behind a Tivoli WebSEAL reverse proxy server, there are some specific
procedures and configurations you must employ to ensure the Sametime server can operate behind the
WebSEAL reverse proxy server. These procedures and configurations are discussed below.
Note: The WebSEAL reverse proxy server must be listening on the default ports of 80 and 443 for the
changes above to work.
To enable a Sametime server to operate behind a WebSEAL reverse proxy server:
1.
You must configure the Sametime server to support HTTP tunneling on port 80. For instructions, refer
to the "About HTTP tunneling" section in the "Configuring Sametime Connectivity" chapter of the
