Chapter 7 Configuring Media-IXT for RealNetworks
Configuring RealProxy
This section explains several issues in the administration of RealProxy.
RealProxy port assignment changes.
Unlike Traffic Manager, RealProxy does not respond to port
assignment changes made to rmserver.cfg when it is sent a SIGHUP signal.
Note that if you change port assignments in rmserver.cfg, the rmserver process must be stopped and
restarted for the changes to take effect.
Configuring RealProxy to listen to IP addresses served by Media-IXT.
Media-IXT serves all network
interfaces (NICs) by default, but RealProxy serves only the primary interface by default. RealProxy can work
in any of these three ways:
• RealProxy listens on only the primary interface (this is the default, so no configuration is required)
• RealProxy listens on selected interfaces (see “To configure RealProxy to listen on selected interfaces:”
below)
• RealProxy listens on all interfaces (see“To configure RealProxy to listen on all interfaces:” below)
To configure RealProxy to listen on selected interfaces:
1. Go to
http://<proxy-address>:<admin-port>/admin/index.html
2. Click on General Setup in the left panel.
3. Click on IP Binding.
4. Click the Add New button
5. Edit the address in the Edit IP Address field
6. Click the Edit button to submit the change
Repeat steps 1-3 for each address that must be active, including the loopback (127.0.0.1) address. When
complete, click the Apply button to commit your changes.
To configure RealProxy to listen on all interfaces:
1. Go to
http://<proxy-address>:<admin-port>/admin/index.html
2. Click on General Setup in the left panel.
3. Click on IP Binding.
4. Click the Add New button.
5. Edit the address in the Edit IP Address field to read
0.0.0.0
6. Click the Edit button to submit the change.
7. Click the Apply button to commit your changes.
RealProxy now automatically binds to all interfaces.
Restart the proxy to have it begin listening on the newly added addresses. Do this by clicking Restart Server
at the top of the page.
Configuring RealProxy for reverse proxy using Virtual IP addresses
When Media-IXT serves as a reverse proxy for hosts using virtual IP address identification rather than
hostname, each proxied host requires a separate virtual IP address.
Use the IP Binding administration command to configure IP addresses. This changes the binding rules in
rmserver.cfg. When IP binding has been changed, stop and restart RealProxy for the change to take effect.
Note that for HTTP, Media-IXT has both ingoing and outgoing binding rules, but RealProxy has ingoing
binding rules only.
