Remote Office configurations for roaming users

I have a large work from home staff that primarily use straight up internet no VPN. The will VPN in for certain operations and will visit the office from time to time. Support said to follow these instructions for roaming users. https://www.manageengine.com/products/desktop-central/managing_roaming_users_how_to.html
However when I follow the steps it won't let me save until I have specified a replication policy. I have no DS servers and no plans to use one.
I tried to setup a replication policy but you have to specify a time and date to replicate the patch's. This does not seem to make any sense to me. Am I going down the wrong path here? I want to manage my remote users over the internet via the forwarding server. Do I need to create a remote office and deploy the remote office client?
