Allow a UDR to specify any routable "next hop" IP address (not limited to the VNet or Region)
It would be great if a UDR could point to an IP in another region or on-premises via ExpressRoute. The problem today is that If someone invests in a NGFW virtual appliance, it can only be used from the VNet where it exists or others that are peered to it within the same region. A UDR should be able to route to any routable address... why not?
Hi Deane, thank you for the feedback, This is a good ask, we are actively looking into it. This is in our road map.

Because that's not how routing works.
The next-hop has to actually be reachable from subnets connected to the router. You know, the next router.
