The UDM-SE I have has a 10Gbps and 2.5Gbps WAN ports:

They also have multi-Gbps switches up to 25Gbps SFP28:

From reports online the UDM-SE won’t actually NAT close to 10 Gbps and the manufacturer doesn’t provide any NAT performance numbers…so it becomes a bottle neck if you have 10 Gbps internet which is widely available and not that expensive my part of the world. (Hong Kong).

The only reasonably priced router I could find about 6 months ago that would NAT at line speed was the TP-LINK Onada ER8411. I ended up going with an all Oanda network which seems to work fine but ubiquiti had originally been my first choice.

Ah nice! And looking further, it appears their U6-Enterprise and U6-Enterprise-IW both support 2.5GbE uplinks.

I recently encounter this as my ISP upgraded me to 10 Gbps over fiber: the UDM-PRO/SE does/can have a 10/2.5 Gbps WAN port over SPF+, but all the Ethernet ports go over to the COU via the same 1/2.5Gbps interface bottleneck [1]. If you really want to use your 10/2.5 Gbps you’re going to have run your services directly on the UDM or go out though the SPF+ port and serve from there via another switch, but then the point of having an UDM is kinda moot. I wish this was more explicitly advertised when I first bought it.
