Glassfish Clustering Question (regarding multicasting)

I have followed the directions for creating cluster with 2 instances on two nodes but, when I run on each machine:
>./asadmin validate-multicast

I only get (loopback)

but, if I run with the --mulitcastport and --mulitcastaddress params defined, each of the nodes can communicate correctly.

I used the same port/address as defined in the domain.xml (which shows in the admin console)...

managing the clusters/instances all works as it should, but, the instances are not able to share/replicate session data without the mulitcast working properly.

I've even followed the directions to set up and test cluster on single machine and the session isn't replicating to the other instance within a cluster...
