Default ports used for JBoss Clustering

[rnappert]

Hi,

assume I have a firewall between cluser nodes deployed. I was wondering which ports need to be opened to make the cluster functioning.

Thanks,

If you have a firewall between two members of one cluster it will be difficult

The problem is that port numbers that are opened are randomly calculated.

Also you might have the multicast stuff by default for inner cluster communication.

I think the best way is to bind against a special IP and route all for this IP and MCast address through the firewall.

A helpful test, for the JGroups cluster communication, is here http://community.jboss.org/wiki/TestingJBoss

This wiki http://community.jboss.org/wiki/UsingJBossBehindAFirewall is only for the communication if the firewall is between JBoss and it's clients.

additional to the above mentioned do not forget port offsets.

Example:

JMX:

Node1 :

127.0.0.1:1090

offset = 100

Node2:

127.0.0.1:1190

e.g. adjustable in bindings-jboss-beans.xml

I totally agree with Wolf-Dieter to bind the adresses, but I'd rather bind all at once instead of binding the most important and common ones first and proof if that solves the problem.

Thanks Wolf-Dieter,

your suggestion works for me....
