HAproxy still needed?

Hello,

I am in the process of building a small renderfarm. Since I use the farm only a few times a year, I want to license both the nodes and the rendering software via UBL.

My nodes have no access to the internet.

Now my question
Based on a recent new installation, do I still have to install the “HAproxy - Cloud License Server Proxy” ? or are the UBL licenses for the nodes as well as for the rendering software forwarded via the deadlines own " License Forwarder" ?

Kind regards
Alex
