QUESTION POSED ON: 29 October 2001
We are in the process of extending our network to all our remote sale reps
by utilizing a VPN. The concern we have is this: How do we extend our firewall
to the remote VPN users? We are currently looking for a firewall/VPN appliance at the gateway of our head office
and a SOHO at the branch, but also roaming user VPN via dial-up connection
throught an ISP.

I'm assuming that what you mean by your question is that you want to provide
firewall protection for your remote users. The way that is done is by using a
VPN, as you suggested. Further, your remote users must always connect to your
home network and never to the Internet directly. All requests for Internet
service must come to the home network via the VPN and back to
the Internet via the firewall. By configuring the remote users this way,
they are
protected the same as if they were directly connected on your home network.
There are many companies that make VPN products that can be configured
to work in this fashion.
