All it does is route packets between a router and a customer's network. One of the customer's boxes has been under DOS attack (SYN Flood, I think), and this causes our Freebsd box to behave strangely. Traffic will pass through the box to anyplace except the router. We can traceroute to anyplace locally from the BSD box, except the router. When we try to hit the router, we get: $ traceroute 208.x.x.65 traceroute to 208.x.x.65 (208.x.x.65), 30 hops max, 40 byte traceroute: sendto: No buffer space available 1 traceroute: wrote 208.x.x.65 40 chars, ret=-1 *traceroute: sendto: No buffer space available traceroute: wrote 208.x.x.65 40 chars, ret=-1 Is there a kernel tweak I can make to prevent this from happening?
