Tips for configuring a load balancer
Enable persistent or sticky sessions
It is important to configure the load balancer to send all Squared Up requests from a client session to the same Squared Up server.
Different load balancer settings use different names for this setting, for example ‘source address affinity persistence’, ‘server affinity’, ‘session affinity’ or ‘persistence’.
For the F5 load balancer it is called Source address affinity persistence. See F5 Persistence profiles
For the KEMP load balancer Source IP Address would be a suitable choice, configurable for each service from Virtual Services > View/Modify Services > Persistence Options. Source IP Address. See Kemp Persistence Methods
If you are having issues with persistent sessions you may need to switch to cookie insert persistence type.

The DNS entry should look similar to this:
