NETGEAR doesn't support all CIDR blocks for static routes?
I tried to set a static route for 192.168.0.0/16 and the RS300 complains that it's an invalid destination. I mean, seriously?

It looks not a CIDR classless support issue; the router thinks the destination subnet address conflicts with its LAN subnet address. It should work if you change the destination to 192.169.0.0/16 or the router's LAN IP to 10.0.0.1.
However, theres should be no conflicts since the most specific route will be matched. I will ask the team to look into it. Thanks.

I believe that is the case. My WAN subnet is in 192.168.30.0/24, and when I added 192.168.128.0/17 it was ok with that, but then when I tried to add 192.168.0.0/17, it said conflict, which was a different message when I tried 192.168.0.0/16. Either way, the RS300 doesn't support longest prefix match routing, which is a very basic feature. There's really no such thing as a "routing conflict."
However, when I connect this in my production setup, the WAN subnet will not be in 192.168.0.0/16, so I should be ok. But it would be good to get this fixed in case someone may actually need this.

FYI, my LAN side is 192.168.75.0/24, so if that is going to cause an issue adding a route to 192.168.0.0/16 or those two /17s, then I'm still going to have an issue unless I change my LAN subnet, which I don't want to do (and shouldn't have to).
Route is downstream on the LAN side...

Hi Wrathchild70,
I just sent you a PM with a link to the trial firmware that fixes the issue.
We will include the fix in a future official release. Thanks.
