Installation guide

A proxy server using the JBoss HTT P Connector can advertise itself via UDP multicast. T o
receive these multicast messages, open port 23364 for UDP connections on the worker node's
firewall.
For Linux users:
/sbin/iptables -A INPUT -m state --state NEW -m udp -p udp --dport
23364 -j ACCEPT
-m comment -comment "receive mod_cluster proxy server advertisements"
If you are not using Automatic Proxy Discovery (see Automatic Proxy Discovery), configure worker
nodes with a static list of proxies. Refer to Section 9.1, “Static proxy configuration” for directions. In
this case you can safely ignore the following warning message:
[warning] mod_advertise: ServerAdvertise Address or Port not defined,
Advertise disabled!!!
