Chapter 6. Using Host On-Demand with a firewall
If you are configuring Host On-Demand to go through a firewall, make sure the
firewall administrator opens port 8999 internally and externally. The Service
Manager listens to port 8999 by default, and the client receives configuration
information directly from the Service Manager over port 8999 by default. You can
customize the port the clients and Service Manager use. To customize the port, see
changing the Service Manager port in the Host On-Demand online help.
In addition to port 8999, make sure the firewall administrator opens any ports that
are being used for functions your clients use. For example, if you have an SSL
session with the Redirector on port 5000, port 5000 must be opened for Telnet
traffic. The following table summarizes the ports that Host On-Demand can use.

Notes:
1 You can change the port numbers with the command WRKSRVTBLE . The
port numbers listed are the default values.
2 The port for as-central is used only if a code-page conversion table needs
to be created dynamically (EBCDIC to/from Unicode). This is dependant
on the JVM and the locale of the client.
3 You can change the config server port. Port 8999 is the default.
4 These ports do not need to be opened on the firewall if you are using
iSeries proxy server support. You will need to open the default proxy
server port 3470. You can change this port.
