The default, 2 seconds, is way too short (generates too much net traffic).

I am wondering how high we can go, and still make the majority of our 
customers' home nat's happy. 1 minute? 2 minutes? 10 minutes?


Thanks for opinions,


Based on my limited experience over the last several years, it would 
appear the Linksys products are not consistent in what they've used for 
nat table timeout values. It seems to vary by s/w version and by model.


I'd suggest starting at something like 60 seconds, evaluate, and reduce 
that value to find an acceptable value. (I'm running at 5 seconds on two 
Linksys boxes without issues, but I've not attempted to identify the 
upper limit on these.)
