Hi Manjeera,

In a typical LB setup, you would have a publishing serving (P1) and two or more front servers (F1, F2, etc.)

P1 is behind the firewall, accessible only inside your private network

F1 and F2 are accessible to everyone, but for security reasons, they don't have access to edit/admin mode.

P1 needs to send remote events to F1 and F2.

And if you're using Self Optimizing Blocks or some other addon that stores data in Dynamic Data Store, then

F1 needs to send remote events to P1 and F2

F2 needs to send remote events to P1 and F1.

Publishing server is not necessary, but then every front server needs to send remote events to all other servers.

Usually, servers are listening on different ports.

For example:

P1 on 5000

F1 on 5001

F2 on 5002

If you've set up remote events correctly (every server will have different services and clients section (1 server, 2 clients per config file.)), you should check if servers can reach each other on a given port.

P1 should reach F1 on port 5001 and F2 on port 5002, etc.

The easiest way to verify this is to use Telnet.

Hope this helps.
