Hi,

I am wondering if this is possible.

What I have read about NAT/PAT is based on IP address.

I want to implement this:

Server1-----------
                  |
Server2-----------
                  |---Router(NAT/PAT)------Internet
Server3-----------
                  |
DNS Server--------

The IP address of Server is not static, But the DNS
name is.

Can I implement NAT or PAT based on DNS name.

For instance, I set up DNS server on Router is
internal DNS server.

Then I want to forward www (port 80) traffic to host
www, and smtp (port 25) to host smtp, not based on
static IP address.

Is it possible?

Any suggestion is highly appreciated.

Thanks.
