Install was perfect, and it's working great. But we noticed something odd. When we do a traceroute from any FreeBSD machine (2.1.0-R, 2.2.1-R, 2.2.6-R) directly to the Cisco, the second of the three packets is *always* dropped (With no exceptions.) Traces carried *past* the Cisco are fine however. Traces run from other OS's are fine, it's just a FreeBSD/Cisco thing. Another ISP I'm friendly with also sees the exact same thing with their FreeBSD/Cisco(s) combo. (Theirs is a Cisco 450.) To carry it further, the source and destination networks don't seem to matter. Traces from our FBSD boxen to their Cisco(s) *also* show the same thing, as do traces from their FBSD boxen to our Cisco. Even if there is no solution, we're very eager to find an answer.
