Hello, I intend to familiarize myself with firewall structuring in the near future, and I've got myself an old Fujitech 486 desktop unit that should do the job. Apparently Bastille is instructive in this avenue, so I thought I'd go in that direction. But as all of this is going to applied later in a commercial environment, I was wondering if anybody would be able to advise as to a decent make of commercial standard Nics. Thanks for any advice. Regards, David.
