NAT to a whole subnet

Sep 18, 2003, 7:26pm PST

With this command: ip nat inside source static network

Is it possible for me to NAT a whole subnet of to the external static ip address of

Eg, if I have a Web servers ip: 192.168.100. 3 &

SQL servers ip: &

Lotus note servers ip: &

Is it possible to use the same ip address for all the servers????


Re: NAT to a whole subnet

You cannot use static mapping for this, because static is for one to one mapping. You will have to use dynamic NAT.

ip nat pool test netmask

ip nat inside source list 1 pool test

access-list 1 permit

I would suggest using public ip to local ip static mappings, if you want these servers to be accessed from the internet, and not use dynamic nat.

Re: NAT to a whole subnet

Thanks, I tried this and it doesn't seem to work.

ip nat pool notes

ip nat pool notes netmask

ip nat inside source list 20 pool notes

access-list 20 permit

access-list 20 permit

Why doesn't this work? How can it be fixed??
