I’ve also had a mix of edgerouter and edgeswitch hardware over the years with my fair share of “please help” posts on the edgemax forums.
My config works pretty fine using either EdgeOS or VyOS. I do see Ubiquiti slowing the pace on their edgemax devices over the last 18 months and thought I would give VyOS a go. Initially it was a no-go, my ISP requires a specific DHCP option to be sent which VyOS didn’t support. A feature request for that, saw it implemented and my migration journey began. In all my time on the edgemax foums, I have yet to see a feature request directly implemented…
VyOS doesn’t play too well with dynamic WAN addresses as it hasn’t implemented some features present in EdgeOS. I was about to give up, but realised a cost-neutral move to a static IP would solve this issue too.
While my use cases are served perfectly well on either platform, I have more interest now in where VyOS is going. Development seems highly active and I have high hopes of that continuing.
