Thanks! These are the sorts of issues I was worried about! Actually, I could probably live with a 30 interface box. It would still be 80% = cheaper for me to build two 30VLAN FreeBSD boxes than one equiv Cisco router or switch.... Cheaper to maintain as well. ---Mike Mike Tancsa (mdtancsa@sentex.net) =09 Sentex Communications Corp, =09 Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers=20 could setup a national IP network."
