Security on Ethernet Network Bridges
====================================

We are seeking a network bridge product that provides an adequate level of
security in its 'filter' process.

A description of the problem:  I wish to link two ethernet networks - called
Inside and Outside.  I am happy for all Inside users to cross to outside.  I
want to restrict Outside users crossing to Inside, and want to check severly
those that try.

I am happy that a (charmingly named) Brouter based on tables of valid
originating addresses would provide a level of security.

If I were to be using X.25, then I am happy that I could have a SmartCard based
challenge.

What I **really** want is a ethernet Brouter/Bridge that at the very least
issues a SmartCard challenge.

Question:  Does such a device exist?  Is it marketed in the UK, and by whom?
If only (eg) USA, where can I buy it?

Replies to the undersigned, who will summarise replies.
