FMP 4 Web Companion and Restricting IP

[joemacuser]

I want to restrict the IP address of my File Maker Database. I know how to do it in FMP 5, but I need to do it in FMP 4. Previously, we used IIS to publish (and limit IP addresses), but I can't do that now b/c IIS on that machine is serving up a different web site and I need to publish using Web Companion in FMP 4. Is their a plug-in for doing this?

There is no real way to do it in FMP 4.x, at least not like there is in FMP 5.x. Perhaps a software firewall or something similar?

You can "hide" things from people outside a desired IP range using [FMP-If clientip.neq.xxx.xxx.*] in the format files, but it's not really achieving the same result. Not too difficult to hack around.
