Well, yes in general...
With that said if your home LAN is behind a firewall then your protected
from outside probes. If the home LAN includes a wireless segment using WPA
encryption with a long random key precludes outside probes. Also if you run
software firewalls on your PCs and configure the firewalls to only allow
File & Print Sharing (F&PS) from specific IP addresses on your home LAN then
that further protects your data.
I think it comes down to a comfortable level of risk. Personally I use the
above strategies on my home LAN and have no need to run an internal VPN. I
do, however, use Secure Shell (SSH) for encrypted secure remote access to my
home LAN from remote sites.
Perhaps if you describe your network in a bit of detail and what your
specific concerns are others could help further...
