All,

I have to nat a complete subnet to something on my network. Currently, the company that we've acquired is on the 192.168.1.0/24 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 192.168.1.0 10.5.5.0 /24

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

In other words, if I ping 10.5.5.15 and I have a host that's address 192.168.1.15, I'll get a response. If I ping 10.5.5.25, but I don't have a host on 192.168.1.25, 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.

Thanks!

John
