Working with the built-in DHCP server on a PA200. Running PanOS 5.0.4
Eth1/3 has the address of 184.108.40.206/16
I have devices with static IPS in the 220.127.116.11/24 range.
I'd like to have the clients in the 18.104.22.168/24 range so I'll need the netmask to be 255.255.0.0, however, there's no way to set that (that I can see) on the PAN.
Setting the DHCP range to 22.214.171.124-126.96.36.199 results in a netmask of 255.255.255.0 on the client. This breaks all connectivity as the gateway is still 188.8.131.52
I've tried setting the range to 184.108.40.206-220.127.116.11 (forcing the netmask to be different for it to work) and still the client gets a 255.255.255.0 netmask.
I looked at the CLI manual and can't find any useful information there.
Does DCHP only hand out a netmask of 255.255.255.0 no matter what?

Changing the IP structure all around seemed to have resolved it.
Reserved address of 172.22.1.1
Client got 172.22.1.0 with a netmask of 255.255.252.0
It would appear that the DHCP settings were 'stuck' and changing everything around completely fixed it.

Go look at your config audits and compare the versions! I wonder if the way that PA tries to "overlay" diffs was flaking out in this case.
A "full commit" might have fixed it too. Hm.
