The issue is that if you set up a FOG across the WAN, you will be subject to the load balancing mechanism deciding where your sessions will live.
For example... We have two sites Site A and Site B These sites have 100MB local LAN's but are connected by a 4MB WAN link. There is one Sun Ray server at each location, and 10 DTUs at each location. If you set up the servers at both sites in a FOG, DTUs from each site may have sessions on the other site during normal operation. This wouldn't be the best use of your WAN link bandwidth. What most customers want is their DTUS to connect to a local Sun Ray server, and if in the case that server is down, connect across the WAN to the alternate. There is no Need to put these in a FOG to do this. The two things that a FOG does is Replication of policy/registrations and load balancing. Your best bet is to use your configuration mechanisms to give the DTUs BOTH servers as connection targets in the preferred order. For example, put both your servers in the servers= line of your .parms file and set select=inorder. The servers= lines will be opposite on both of your servers.
