Thread: Need Router That Routes Multiple External IPs

Like the title suggests: I can't seem to stumble on a router that can handle forwarding of multiple external IP addresses.

Anyone who has experienced the Software Router Win route will understand. That application made it possible have a block of static IP addresses from your ISP; and the router could be configured to forward a 'Listening' (external) IP/Port combination to a 'Destination' (LAN) IP/Port combination.

The reason for this: We have a standard network using SSL Port 443 for OWA and 'company web' applications on Windows Server 2003 SBS. We now want to implement a bank check reader to the mix. It will be attached to a client computer on the LAN, and will also want to use Port 443 for its own secure communications. The easiest way to accomplish this is to assign the device to one of our external static IPs and have the Router table handle that (external) IP/Port combo, which will keep it away from the main (external) IP/Port combo used by the server and network in general. We used this trick when we had the old Win2K/Winroute box setup as the gateway/router.

We are now using a standard Netgear Router (WNDR3300) as the Gateway/Router, but that does not have the capability I need.

Need suggestions on a new Hardware Router (not interested in any suggestions of other box/software setups)...

Thanks

I'm running a Cisco 1700 and it pulls two static IPs and forwards them to the appropriate internal IP using NAT.
The following should work on any Cisco router and will also allow other computers to do dynamic NAT on the fast ethernet0 interface. Make sure that you set the ip nat inside or ip nat outside on your interfaces

ip nat inside source list 7 interface FastEthernet0 overload
ip nat inside source static 192.168.1.80 <external IP 1>
ip nat inside source static 192.168.1.235 <external IP 2>

access-list 7 deny 192.168.1.80
access-list 7 deny 192.168.1.235
access-list 7 permit 192.168.1.0 0.0.0.255.

Thanks for the detailed listing.

I'll check it out.
