Consider the following when using the WAN Gateway role in mixed-version environments:

  • WAN Gateway Role assignment is only available on PingDirectory servers version 3.5 and later.
  • Legacy servers earlier than 3.5, are never selected as WAN Gateways.
  • Updates from legacy replication servers forward to all replication servers and do not funnel to a single WAN Gateway, which increases WAN during replication.
  • Updates from remote WAN Gateways forward to the legacy replication servers, which increases WAN traffic during replication.
