Astaro is a Linux based solution that packages all these items nice and
neat for you. If you don't mind doing the setup and config you can
accomplish all of this.

iptables (fwbuilder is a decent object based gui, firestarter may be a
little simpler)

squid with a redirector, squidguard or dan's guardian will do content
filtering.

Openswan will support win32 vpn clients, probably the trickiest piece,
their are also ssl based solutions which will work fine when their are
minimal sessions, meaning you don't have a slew of simultaneous tcp
traffic.

I don't think this will be anywhere as friendly as the astaro from what
I have seen, but depending on your skill set and willingness to learn
one can easily provide all you require. You may be able to use webmin
and what it supports for a common interface.
