VPNs - A Routing Warning

VPNs are great things.  They allow secure remote access to your resources, either for your home or your job.  At work the solution is simple to use because typically someone else sets it up for you.  But if you are that person that does the setup (either at home or if you're the "network person" at work), VPNs can be complex.  I'd like to cover a quick thing to watch out for targeted at small VPNs, especially since I talked about VPNs in a previous ZoneMinder article.
