Good afternoon!

I have a question regarding my Pritunl VPN setup. My environment is multi-host without NAT enabled. I have two hosts, and AWS Route Advertisement is configured and operational.

I noticed that Pritunl creates two routes per server in my AWS subnet route table. One of the routes corresponds to the server’s CIDR, but the other one is a CIDR that I don’t recognize. Could you please explain what this second route is and why it’s necessary?

Thank you!

There is an internal VXLAN network from the range `100.97.0.0/16` that is used for routing in multi host configurations.
