• Using a load balancer in SNAT (source network address translation) mode is recommended for ease of deployment, however be aware each SNAT IP address on the load balancer limits the maximum number of simultaneous connections to 65,000. If you deploy load balancer in SNAT mode, ensure you configure a minimum of one SNAT IP address for each group of 65,000 users. (The open number of connections generally corresponds to the number of active users.) For example, in a deployment supporting 100,000 users, you would configure two SNAT IP addresses.
  • If you use a DNAT (destination network address translation) load balancer for your Enterprise pools, the following is required:
    • Each pool must reside in a distinct IP subnet from other pools, because the Front End Servers in each pool must reside in this distinct IP subnet.
    • For a pool in the expanded configuration, only the Front End Servers must be placed in this distinct IP subnet. All other roles – the Web Conferencing, A/V Conferencing and Web Component Servers – must reside outside the distinct IP subnet for the Front End Servers. There is no additional restriction on how these other roles can be placed on the network.
