I read the following in a routing book from Cisco, but they didn't give an example config. Can someone show me how this would be configured (just for one of the servers)? Also, can NAT like this be done on the 3750 SMI? Thanks!

In Figure 4-10, the enterprise has a mail server at the local address 192.168.50.1 and an HTTP server at the local address 192.168.50.2. Both servers have a global address of 206.35.91.10. When a host from the outside sends a packet to the inside, the NAT examines the destination port in addition to the destination address. In Figure 4-10, a host has sent a packet to 206.35.91.10 with a destination port of 25, indicating mail. The NAT translates this packet's destination address to the mail server's, 192.168.50.1. A second packet from the same host has a destination port of 80, indicating HTTP. The NAT translates this packet's destination address to the Web server's, 192.168.50.2....

In a pix it would be...
static (inside,outside) tcp 206.35.91.10 25 192.168.50.1 80 netmask 255.255.255.255
static (inside,outside) tcp 206.35.91.10 80 192.168.50.2 80 netmask 255.255.255.255

I know on a router I can do:
ip nat inside source static tcp
Can I configure a pool of outisde ip's to map to the one internal ip, or can I only do one-to-one?
And does anyone know if this is supported on the 3750? I cant really find any info on what NAT features are supported?
Thanks!
