- I'm trying to get information on how to configure a firewall system --
- that is, a system through which we could connect our internal development
- network to the Internet and maintain a modicum of confidence in its
- security. We have a SCO ODT system which we connect to the Internet via
- dial-up SLIP, and we want, for various reasons, to connect this system to
- our internal network, but we are concerned about providing some
- reasonable security. The scheme I have in mind is basically that the
- firewall will not be able to forward packets between the two network
- interfaces (the SLIP link and an Ethernet hose). In this scheme, our
- users could telnet from internal systems to the firewall, and from there
- could perform whatever Internet stuff they wanted. The firewall should
- be able to telnet or ftp to either internal systems or to external
- systems, but would refuse any (I *do* mean any) packets bound from the
- external systems to internal systems (i.e. it wouldn't function as a
- gateway at all).
-
- I would appreciate suggestions on how to set up such a firewall, and if
- this is a reasonable idea. Replies via email to pmj@roadnet.com are
- welcome, as are posted replies. If folks are interested, I'll summarize
- and post.
-
- Thanks,
- Pete.
