Nighthawk R7000P saying "Invalid Subnet Mask" when trying to add static route.
Hello all! I got a Nighthawk R7000P not too long ago and I cannot add a static route, because the router says "invalid subnet mask" even know I am pretty sure that subnet mask is valid. I am not sure...

Your example looks fine to me, but that might mean very little if
what you're actually doing is different from your exhibit.
"255.255.255.0" would normally be a swell subnet mask, and the error
message could be misleading. Or the fictional garbage which you're
posting could be misleading. With my weak psychic powers, it's tough to
say.

I have a better idea. Let's just say what you're actually doing, and
stop wasting everyone's time. If these addresses are all private, then
there's no reason to hide any of them. If they're not all private, then
you might need to explain in more detail exactly what you're doing.
Also interesting would be some information on which of these routers
is connected to your ISP (and how), and how they're connected to each
other, and how they're configured.
