Thanks for the explanation.
At the moment we chose one cluster on staticip and other cluster node on vpnip
both machines are completely different.
We can add more machine in staticip works fine but still want one machine on
vpnip so we can connect without changing the firewall rules.
Can two cluster one on vpnip and other on static be linked in any ways?
or the only way to go forward is use non clustered ejb on vpn node.
There may be stuff you can do, but I'm not sure what your goals are. Simplest is separate clusters for the staticip machines vs the vpnip machines. Those two clusters can be linked in some ways, but that gets complicated and before getting into it I'd need to know in what ways you'd want them linked.
