Verification on what I'm seeing with nat

Answered Question
Jun 16th, 2009


I have to nat a complete subnet to something on my network. Currently, the company that we've acquired is on the subnet, and we have devices on that subnet. I'll need to nat them to something else.

What I've noticed is that if I do the whole network like:

ip nat inside source static network /24

It seems to allow the host to correspond with the translated host one-for-one.

In other words, if I ping and I have a host that's address, I'll get a response. If I ping, but I don't have a host on, I'll get a timeout. Does this seem right? This is what I want because I'll need to translate the complete network and won't know what addresses are where until we do the complete transition.



I have this problem too.

Hello John,

your understanding is correct this is network static nat

having the local subnet and the global subnet the same prefix length there is a one to one relationship.

This can be very handy.


Hope to help
