Good morning, 
 
 i have an issue with all appliances i install where ther need to be set up a Site-to-Site VPN and NAT-T needs to be enabled. 
 the option to turn on NAT-T is grayed out every single time. is this a bug? or am i doing something wrong? 
 
 With kind regards Rene

I made a case #7339326 for this issue and i got a response: 
 It's not possible to use NAT-T with a Site-to-Site IPSec VPN at this time unfortunately. It will be possible in version 17.
