Friends of mine have a small business and would like to
set up a VPN to allow up to five remote users to connect.
They're mainly interested in file sharing and IM/netmeeing.
They are using windows clients.

The enterprise grade appliances on the market are way out
of their league, so I'm wondering if anyone is aware of
an SMB solution that might fit their budget. I suppose if I
could narrow their requirements to just file access, I could
push an SSH solution, but they seem to want a true VPN.

Another option is to take an old PC and install something
like OpenVPN, which is fine, but I'd rather avoid a
science project if I can.

Thanks.
