Setting up Hassio with DuckDNS but takes me to my synology

Hope I am posting in the right area. So I set up duckDNS and Porter forwarding on my router Eero Pro so I could connect my smartthings hub. It all starts working for a bit but later if I try to log in threw duckdns it takes me to my old Synology 1412+ I use for surveillance station and back ups to my computer. I do not have a open port for the synology on my eero router other then port 9000 for surveillance station. I followed these instructions https://www.youtube.com/watch?v=jkBcGl7Vq8s

I run my Hassio VM on a seperate unraid machine. Anyone have a suggestion?

So I am running 5.9 and noticed under system/host system/ip address. do I need to set the the HA to static and keep the same ip adress its using now?
