Pros

  • UCG Fibre seems to fit the bill as you can reassign all ports.
  • I have a UCG-Fiber and U7 Pro Wall at home, but still went ahead and I brought 2 of UDR7's during the Black Friday sale :)
  • consider the UCG-Fiber setup which is like having a mini UDM Pro, but with a better CPU in a compact design as the better long term option.
  • If you have a total of <100 devices, only want to run Network and Protect, and have >2Gbps Internet, get the UCG Fiber. It's WAY better for straight-line speed than the UDM Pro Max, especially if you have fiber with PPPoE or want to have...

Cons

  • Why on God's green earth are you buying a Cloud Gateway Fiber? Why are you looking at ANYTHING that does higher than gigabit unless you have an immediate plan in place for a fiber upgrade in the <2 year immediate future? I was assumin...
  • Switching on the router means load on the CPU. Load on the CPU means less CPU horsepower available for, you know, routing. From your ISP to your local network. Also, if you use the 10GbE RJ45 WAN port, that shares a single 10G pipe with...
  • I had a similar issue with my UCG-Fiber and I was getting half of the speed I was paying for.
  • I switched from an EdgeRouter X to a UCG Fiber, and everything actually became much worse after that.
  • I guess you are repurposing old equipment rather than upgrading to a UCG fiber for example.

Why on God's green earth are you buying a Cloud Gateway Fiber? Why are you looking at ANYTHING that does higher than gigabit unless you have an immediate plan in place for a fiber upgrade in the <2 year immediate future? I was assuming if you had bought 2.5G switches, you actually had some reason to do so, but if you've got 35Mbps WAN then anything faster than gig is a complete waste on the router side.

Switching on the router means load on the CPU. Load on the CPU means less CPU horsepower available for, you know, routing. From your ISP to your local network. Also, if you use the 10GbE RJ45 WAN port, that shares a single 10G pipe with the four 2.5GbE ports. That means you have a total of 20Gbps worth of ports sharing a single 10Gbps link - bad news if you're actually utilizing that 10G WAN port.

For the router I would go with the UCG Fiber. Dual SFP+ ports make it relatively future-proof.

but ucg fiber is more stout. If you have pppoe the fiber has action real hw support for you

UCGF will route packets with ids at over 9gbps. Even if you dont need that, thats headroom for other functions. The UDMPM will not.
