Netgear DGND3700v2 & Vodafone Suresignal v3 Issues

Hi All,

I have a very popular question to ask for help on. Basically I have a DGND3700v2 router connected into a GS108 & GS116 switch. I am trying to get the Vodafone Suresignal v3 (herby known as SS) to work and am failing miserably. I have read many posts that recommend forwarding various ports for the device (50,123, 500 & 4500), which I have done, without success. I have added the IP of the SS to the DMZ also, and still no luck. UpNp is off, but still doesn't work with it turned on.

I have reset the SS, deregistered it and re-registered it, all to no avail. The section on the Vodafone website for the SS marks it as active but I still get the single red light with a slowly pulsing globe light.

Any ideas??

Cheers
