Re: NAT/PAT

Break down the NAT configuration into smaller subnets. Do not translate everything to a single IP address.

If you have 128 Public IP addresses, you can create 128 dynamic NAT assignments.

With that said, I recommend using a FireWall (ASA or PIX) for this type of task as the performance is better when doing many address translations. It can be done on a powerful router (7200 or above) but a FW performs better.

HTH,
