Sky router won't let me set Default DMZ Server

[tobyh]

I am trying to set a value in the Advanced -> WAN Setup -> Default DMZ Server field, but the Sky SR203 router will not accept the value when I click Apply.  I've tried everything including reboots, etc but it just reverts back to 0.0.0.0 every time.

The IP I am putting in is 192.168.0.2 and this is a DHCP reserved IP that is given to a 3rd party router that I am setting up behind the SR203 (double NAT).  I can see the reservation is working fine and I can see the IP connecting on the interface connection on the 3rd party router.  I just can't get the SR203 to commit the value in the Default DMZ Server field.

Any ideas?

@tobyh if a simple reboot doesnt clear the issue reset t he Sky hub by pressing and holding in the reset pin for around 20.seconds.

In case its of use to anyone else in the future...

I couldn't get this working so I called Sky support and it turns out the problem is caused by Google Chrome.  For some odd reason the fields show as "0.0.0.0" in Chrome but, as soon as the agent got me to switch to MS Edge, the fields showed the correct IP address.  So it looks like Chrome did process and apply the IP address change that I submitted but, for whatever reason, it wasn't subsequently able to display them in a browser window.  Most odd, but Microsoft Edge sorted this out.
