You *are* off your rocker to get a PPro200 128MB RAM. Depending on you bandwidth needs, you only need a P-133 with 64MB of RAM :-) I have a 686-120/P150+ with 5 ethernet cards and about 1000 kbps flowing through it - i.e. a 66% utilised T1. CPU utilisation is about 10%, and a significant amount of that is servicing interrupts on the PCI-NE2000 ethernet cards, and checking the 470 ipfw rules I have loaded. Use de or fxp ethernet cards in preference (the two busy cards in my box are de type). I'd recommend a 686-150/P200+ to keep packet latency down. Use gated for BGP peering. Dennis will probably remind you to look at www.etinc.com regarding synchronous serial cards. /* Daniel O'Callaghan */ /* HiLink Internet <http://www.hilink.com.au/>; danny@hilink.com.au */ /* FreeBSD - works hard, plays hard... danny@freebsd.org */
