Hey, do you necessarily have to have /23 subnet configured on this device?

Why not just set it to /16 or something else - I believe network-wise it will work - but maybe you want to have it in case of security?

Hello Brian, have you managed to overcome this issue. I've got the same one

Thank you

I see this error on occasion as well using the VSA and CMC version 9.5. I always assumed the cause was my default gateway not being reachable on the SAN (layer 2 only), but was never positive this was the cause.

that is odd and it "should" work.  I would contact support over this one.  Must be some sort of bug w/ the fact that you are using a pubilc IP range... or, if you don't actually own those IP addresses (aka you aren't w/ the NIH) there might be something else going on.

personally I don't like the idea of a SAN using real public IPs.
