Pros: It does exactly what the product documentation says it will, and it ONLY does that. See Cons for example of why this might be misleading. We've had many problems with this device (we own 2), this example is one of the many ways this product disappoints.

Cons: Docs say that it supports multiple IPs per interface. This is true, HOWEVER those IPs must be on different networks. So for example, if your ISP gives you 5 Public IP addresses (they are usually on the same subnet). You cannot use the 5. You can only use the 5 addresses if they are on different subnets. What ISP does that?? Unfortunately, we assumed that multiple IPs per interface meant what most normal folks would mean by that statement. The implementation of this "feature" makes it useless in practice.

Overall Review: These kinds of issues are deeply imbeded in this product. They've advertised feature, but it only works in a very specific and constrained scenario that renders the feature useless. My advice, do't go there.
