Router NAT

Hello all

we want to configure a dynamic NAT on a router.

The NAT must conserve the same last octet.

10.a.b.c nated to 20.a.b.c

Is it possible with IOS CISCO ?

Thanks for yours reply

Hi

Ok for the Static NAT. But the problem is we have a lot of host (150). We will like a NAT automatic. Is it possible with a pool for exemple ? The objective is 10.a.b.c to 20.a.b.c for exemple

Re: Router NAT

Yes,

you can use static Nat or using a pool with the 20.a.b.c in dynamic NAT.

Re: Router NAT

Ok but when I configure a pool, the NAT don't translate with the same IP adress last octet.

Re: Router NAT

A pool is just that - a group of IP's sitting in a bucket, waiting to be called upon. If you NEED, for example, 10.1.1.1 to be translated to 20.1.1.1 using Cisco NAT, you need to go with multiple static entries (as was mentioned by an earlier poster) rather than a pool.

Re: Router NAT

Ok I found the command line

it's :

ip nat outside source static network 10.0.0.0 1.0.0.0 /8

And that's work !
