Multi-NAT

[kaywilliams]

Hello all,

I have a small business network with multiple systems on a local lan.  I would like to expose two of these machine on the Internet using static IPs provided by my ISP. Both of these machines provide web services over ports 80 and 443, and thus port forwarding will not meet my needs.  The way I have addressed this issue in the past is to use a router with "multi-NAT" or "many-to-many NAT" support. Alas, the router I was using is no longer working and the company no longer provides a similar offering. In speaking with CISCO customer service today, they suggested that one of the routers in the CISCO 800 series should meet my need.

So my questions are:

1. Is anyone out there using an 800 series router to address a similar scenario?

2. If so, is it possible to configure this scenario (e.g. Multi-nat) using the Cisco Router Web Setup (CRWS) Tool?  I'm not familiar with IOS and would prefer to skip the learning curve.

Thanks for your suggestions and advice.

Kay

Cisco Small Business RV series routers such as RV042, RV082, RV016, RV120W, and RV220W support a feature called one-to-one NAT, which supports your scenario. All of the above routers can be managed by a Web GUI.

Here you can find the administration guides for these routers.
