Basic Protection

["Frank R. Boecherer" <frank () computica com>]

Hi....  this is my first time visiting this list and my first post.  I've been a
subscriber a VPN list (vpn () listserv secnetgroup com) for some time.  I have a question
which is firewall related so I was referred here.  Since I haven't read all the posts yet,
if there are some dealing with my questions, a quick pointer to them would be appreciated.

Thanks

Frank

===========================================================================
I have some clients with NT server (typical vanilla setup) and they want to hook up DSL
for Internet access.  If NAT or Proxy Server is used, is there enough protection or is a
full firewall needed.  To phrase the question another way: How do I allow a client to have
fast Internet access for all the workstations without haveing to spend a lot for firewall
protection?

With all I've been reading, it seems like the only secure way to go is with a firewall.
But if NAT is used and the IP address of a workstation on the internal network isn't known
or available to the outside, is it safe?  Does and ISP provide security so that I don't
have to worry about it?

Thanks
