check to see if WAN IP address has changed in dd-wrt

[gregtompkins]

Hello,

So I have this if I snmpwalk:

ipAdEntAddr.71.193.1.35 = IpAddress: 71.193.1.35

I want to know when the value changes, I think I'm getting it a little wrong. Here's how I created the item and the trigger but it's not working. I'm not sure if this is Character or Numeric for one. And this is the trigger expression: {router:IPAddress.diff(0)}=1

What did I do wrong?

Thanks!
