In theory, 192.168.0.1 with mask 255.255.0.255 would match every .1 in 192.168.0-192.168.255. It's just very uncommon to have subnet masks that don't have the 0-bits at the end, but it may work depending on the device and if the configuration is accepted.

Subject: How do I wildcard the third octet of a subnet?
Basically I have a SSID that I'm using for an internal service. I have 45 sites I need to deploy this SSID to. Each site has a private subnet of 192.168.xxx.0/24 where xxx is the site id. So I'd like to be able to allow 192.168.xxx.1 for each of the 45 subnets but block access to the rest of the 192.168.xxx.0/24 subnets. Basically restrict most access internally but allow for internet access.

Maybe what you want can be accomplished in a different way. The way you describe it would involve alot of work to accomplish. What product are you using and what are you trying to block/allow in detail?

I need to allow access to the default gateway for 40 subnets, but I want to restrict access to the rest of the subnet. is it possible to write a firewall rule that would let me wildcard the third octet of the subnet? For example I want it to be 192.168.xxx.1 where x is any subnet.
