Jeremy, I'd love to help. What does a trace from the Cisco to the fbsd box show? Cisco does traces a little different that UNIX boxes. We use UDP on the outbound, and receive icmp on the inbound. Also, what version of the IOS are you running? I'm sure our engineers here would love to know that FreeBSD and Cisco products have a conflict. I'll do more reasearch, and let you know what I find.
