how to setup firewalls for clustered datagrid?

[li.dai]

Hi there,

I am trying to set up a clustered datagrid on 3 servers, anyone knows what are the firewall rules between these 3 servers and the firewall rules for others to access this cluster?

thanks in advance!

If the firewall is between the servers you need to open the ports for JGroups, if you use UDP configuration you need to allow multicast as well.

Depend on the mode you use you might need to open the hor rod ports for access also.
