I'm new to the list and quite inexperienced with firewalls and security
issues as discussed on this list. I'm acting as Systems Administrator at
the Polytechnic and we have recently attached to the internet. Due to serious
worries w.r.t. security of our systems I did not attach our network directly
to the internet. The only 'internet activity' users on our network can
partake in is email. To do anything else they dial in to zebedee, the system
connected to the internet. See below.

======================================================================
which all our clients live
Presently this seems to work fine, with mail. As our clients are becoming
more aware of the facilities available to them from the internet I must allow
them access to the internet from our 'Big bit of ethernet'.
So, the question! Where do I start? Is there any literature I can read that
will help identify strategies I should adopt? Is there any hardware that I
should consider purchasing to help me out?
Any comments/ideas/pointers would be very greatly received.
Chris.
