NAT Timeout values

In older versions of the FOS, you could set the timeout on a nat command - why was this taken away?

Re: NAT Timeout values

The options available were:

address: Network address to be translated

dns: specifies that DNS replies that match the xlate are translated

hh:mm:ss - the timeout interval for the translation slot. However, timeout only occurs if no TCP or UDP connection is actively using the translation.

This comes from my study guide:

Re: NAT Timeout values


Wow, and I thought I had been working on PIX's for a long time...

Anyway, I never had experience with this command set but I think I do see what this command did. Today, we replace this functionality with the timeout command. See this link for more info:

Hope this helps.
