Ick.  Multi-function devices are in general a bad idea.  Frequently they
end up restricting the end user to a small subset of possible
configurations and uses.  In most cases you're better off with a
dedicated device serving a specific purpose.

You'll want to be careful with these devices and make certain they
support your intended use.  As these are hardware solutions, you are at
the whim of the manufacturer as to what it can and can not do.  Some of
these devices didn't support GRE packets (necessary for PPTP based VPN
connections) or IPSEC connections.  Many of these short comings have
been addressed by the manufacturers, but these problems can (and in some
cases still do) exist.
