Given a LAN with default gateway of 10.5.1.1 and subnet of 255.255.0.0
The DHCP range is currently set in the range of 10.5.2.1 to 10.5.3.254
The 10.5.1.x range is reserved for static IP’s.
I want to increase the DHCP pool ( the 10.5.2.x – 10.5.3.x range is too small )
Is this DHCP scope limited to the 2.x and 3.x range because of the 255.255.0.0 subnet?
I cannot change the subnet in this scenario. When I try to add another range to the DHCP server ( i.e 10.5.4.x ) it will not allow it ( illegal range? )….
It’s a Sonic Wall .. Model: PRO 300 (CPU: StrongARM / 233 Mhz) Firmware version: 22.214.171.124
As posted in the comments, SonicWall does routinely limit the number of devices their products will manage. Sometimes they offer “licensing upgrades” as options and sometimes it is a hard limit based upon the particular model.
