Hi everybody,
I'm having a little problem with my iptables letting JBoss Cache work
properly. What protocols/ports Jboss cache needs open to work properly
in iptables?
I have this rule based on my jboss config file:
-A RH-Firewall-1-INPUT -s 239.255.0.2 -m udp -p udp --dport 48866 -j ACCEPT
But it doesnt seem to work. *If I turn off iptables JBoss Cache Cluster
works fine*. I'm also curious if its normal everytime I restart cas
servers the port is different:
-------------------------------------------------------
GMS: address is 194.117.42.201:50094
-------------------------------------------------------
-------------------------------------------------------
GMS: address is 194.117.42.201:52537
-------------------------------------------------------
-------------------------------------------------------
GMS: address is 194.117.42.201:37420
-------------------------------------------------------
etc..
Thanks,
Francisco
