NAT IN CATALYST 6509-HOW TO DO IT?

[wmunguiam]

Hello friends,

The LAN CAMPUS is conformed by more than 20 VLANS and all the PCs can go to Internet.

Now I have a new network cloud and I have to attach that network into my campus.

To do that, I have a Public IP Pool to do translation.

But I just need that some IPs (from diferent Vlans)could go to the new Network while keep having connecivity to Internet.

So my Question is:

I am not interested in perform Static NAT.

I wonder if I can NAT a group of IPs (in different subnets) with the Public POOL. i.e: group to group.

I have a PIX 525. I could do it in that PIX but I think It could be better to do it in the Catalyst 6509. (Because the Pix CPU percentage is High-and sometimes I have problems)

How can I do NAT in C 6509?

I am attaching a referecial picture.

sounds like an ACL would be a simpler approach.

Hi bosalaza:

yes, I think ACL will help so much...

Look I need to translate only this IPs:

172.16.8.56

172.16.24.85

172.16.33.95

172.16.86.56

172.16.125.81

172.16.157.89

To this Public IPs:

200.xx.45.170

200.xx.45.171

200.xx.45.172

200.xx.45.173

200.xx.45.174

200.xx.45.175

But whitout Static NAT.

And do it but in the C6509.

I have no enough experience to perform NAt in C6509.

Thanks in advance.
