[jboss-user] [Clustering/JBoss] - Re: JBoss Cluster on Multihomed zone

A few key points:

1) If you don't tell JGroups what address to bind to, it doesn't bind to all interfaces, it picks one. So, on a multihomed machine, it's always best to tell it which one to use.  

2) There are multiple JGroups channels in an AS (in 4.0.3.SP1, there are two).  Http session replication uses a different channel from the one configured in cluster-service.xml.  It's channel is configured in tc5-cluster-service.xml.

3) If you don't want to manually edit those file to set bind_addr, it can be done globally by starting jboss with the -b switch

./run.sh -b 3.183.158.1 -c all

Doing that sets a global override.

Why it works on 3.183.158 and not 10.50.1 is likely the result of some OS/network layer configuration on your machine or on the networking hardware between machines.
