How to Change IP & DHCP IP Pool

[diveredd]

I just got my Verizon Fivespot and I'm having trouble changing the default IP address on the LAN side.

Its currently 192.168.0.1 with a DHCP pool of 192.168.0.100 to 254.

I would like to change it to 192.168.5.1 with a pool of 192.168.5.100

The problem is that when i click on the field to change the ip address it won't let me change it.  

Any help???

Thanks,

Ed
