We are setting up a DMZ environment and we have 3 load balanced Forms servers internally. In the 'Hosting Laserfiche Forms 11 In a Perimeter Network (DMZ)' whitepaper we are using the 'Two Forms Servers with Two STS Instances' configuration. It talks about making changes on the 'Internal Forms Server'. Since we have 3 internal Forms servers, do the changes need to be made on all 3 servers?

I am asking because I made the change to the internal primary Forms server only and when I am connected to one of the other two servers in the LB and try to perform certain tasks it tells me to check the routing service.
