Smartlink on 3.2.12?

I thought I had gotten my bugs worked out but I was at our camp this afternoon getting the water going and things ready for summer and decided to try Smartlink from there with the iPad. This is where most of my remote use is. No joy....

I came back home (only a few miles) and checked everything out and I am doing dhcp with a reserved IP for the 6500 and everything looks right. I deregistered and restarted and it seemed OK but the test fails and Smartlink isn't working for me. Any hints what I've forgotten? I did more than a few cold starts getting through some issues with 3.2 so I figure it's something with that. The problem with Smartlink is it worked so darn good over the last couple of years I've forgotten a lot of the mechanics behind it!

On the bright side, the water in the camp works and the fridge and ice maker (key camp essentials) are in full operation!
