Multiple static IP through one interface (Cisco 1711)

Hi everyon,

I hope this is the right place to post this question. I'm rather new to Cisco routers, but I've found outstanding performance gain over the cheap ones we used to use. I have four servers connected to a private network behind my Cisco 1711. I have 5 static IPs from my DSL ISP. I need to get a second static IP through the router to a server which is already assigned a private IP.

My network goes like this:

DSL modem ---- Static IP 1 (Ethernet) Cisco 1711 (Fast Ethernet - vlan1) 192.168.1.x ---- Switch ---- Servers 1-4

Server 1 is setup with one private IP 192.168.1.21. Ports 80 and 443 are being forwarded from static IP 1. I need to somehow setup a second static IP and forward the the ports to another private server. Is it possible to setup two static IPs on a Cisco 1711 through te same ethernet interface?

I use Cisco SDM to configure the router since I am very bad with the commandline IOS.

Any help / suggestions are greatly appreciated.

Thanks.

Your relevant configuration sounds like this:

! interface ethernet ip address ip nat outside ! interface vlan1 ip address 192.168.1. ip nat inside ! ip nat inside source static tcp 192.168.1.21 80 80 ip nat inside source static tcp 192.168.1.21 443 443 !

For your second device you probably just need to add:

! ip nat inside source static tcp 192.168.1. 80 80 ip nat inside source static tcp 192.168.1. 443 443 !
