NIS 2009 Learn Automatic IPv6 NAT Traversal Taffic

Hello Symantec/Norton Community,

 

 

I'm sorry if I'm wasting someone's time here but, with regards to my question, I was looking in the 'Internet Settings' tab in NIS 09 (fully updated), and under the heading 'Smart Firewall - Advanced Settings' it came up with a window of options. Now my question is - 

 

What is 'Learn Automatic IPv6 NAT Traversal Taffic'?

 

I'm hoping if someone could explain what does or if is it important feature to have on, or just leave that particular feature off. I'm only asking this question because I'm curious of what is, does and if it needs to turned on as a important feature.

 

 

Thank you for time and patience. Replies are greatly appreciated.
