How to enable NAT Traversal in XG IPSEC S2S?

Question

Hi, we have several XG's running in MS Azure, on SFOS 16.05.6 MR-6... 
 Every time I've tried to turn on NAT Traversal in the IPSEC Site-to-Site VPN settings, it's not let me enable the CheckBox. 
 Now, I'm trying to do a VPN between 2 which are both in Azure and the logs are showing NAT T is necessary. 
 
 How can I turn it on??

Hi Barry, 
 you can't change the NAT Traversal Option after creating a VPN definition. 
 Please Try to create a NEW VPN Definition with NAT Traversal enabled.
