Overly restrictive DHCP server configuration in RBR850

ello

 

The DHCP server in firmware version 3.2.18.1_1.4.14 is overly restrictive in that it does not allow the pool of addresses to use the entire available subnet.

 

My RBR850 IP address is 192.168.2.1 with subnet mask 255.255.254.0, this allows terminal addresses from 192.168.2.1 through to 192.168.3.254.

The DHCP server funciton only allows addresses up to 192.168.2.254, and the first three bytes are not selectable.

My preference is to have the 192.168.2.x range for fixed addresses and 192.168.3.x for DHCP

       I doubt that these consumer-grade routers were intended to work with
    subnet masks narrower than "/24".

       Change your preference, or get a more serious router (or DHCP
    server)?  A DHCP pool like ".100" - ".199" should make recognition
    pretty easy (without over-taxing the router).
