[jboss-user] [Clustering/JBoss] - More firewall ports for cluster than in config guide?

[bmelloni]

After resolving a number of issues I got a 2-node jBossEAP cluster mostly working with the Windows Firewall disabled and settings at default values except for those required post-installation.

Attempting to re-enable the firewall I opened the ports indicated in the Server Configuration Guide, tables 9.1 and 9.2.    I get the errors below on other server (stayed running, first node, no firewall on it).  It looks like TreeCache is using ports in the 1000-2000 range that change at each server start.  As shown in the attached log snippet, the problem goes away as soon as I set the firewall back to OFF.

Is there a known range for those ports?  Or is there a configuration item that will lock the ports so that they will be reused at each start?  In a different post someone thought I was using TCP instead of the expected UDP multicast, even though I used defaults.  If the defaults are wrong for the multicast choice or something else is causing it to fail over to TCP, where do I fix them?

Thanks.

BTW, yes I know that since I am using a commercial version I can open a support ticket... I am using the forum until I get my support credentials.
