I have a Cisco PIX 200 MHz version that has about 20 3DES IPSEC tunnnels going through it. On the other side of the PIX I have Dual T1 bonded (CEF) for throughput. Although the PIX shows only 10% cpu usage, how will I know this thing is getting taxed or invest in another? My company doesn't have the $$ to invest in a 7200vxr or anything like that. Thanks, Joe
