@Theeyeinthesky I think I misunderstood your question., you can use wireguard to solve your problem. here is a guide, on remote site set allowed ip to 0.0.0.0/0 then all trafill will go out to main...

@Theeyeinthesky use sd-wan. gobal settings, sd-wan or folow this guide https://community.tp-link.com/en/business/stories/detail/502060

@Mellx1 Yes, this is for rj45 copper cable. https://www.omadanetworks.com/en/business-networking/omada-accessory-module-cable/sm331t/

@Mellx1 these should work, you must have A and B modules for them to work together, you cannot have two of the same on the same fiber cable....

@Mellx1 what type ftp module? fiber? multimode, singel mode, or rj45 module

@PrzemekW1 you probably have cloud essential, there are not as many functions as in, for example, cloud standard or self hosted controller
