i've got a freebsd system: 4.4-STABLE FreeBSD 4.4-STABLE #1: Wed Nov 14 04:46:33 EST 2001 that's acting as a primary router at a small isp. This system does NAT using natd for 10 private class c's inside it. When making routing changes, for example routing an entire subnet or class c through a different interface, there appears to be a significant lag before the new routes are picked up. netstat -rn recognizes the routing change reporting the correct new route after changing the route by: route delete 10.0.0.0/24 route add -net 10.0.0.0/24 -interface [new-interface] I'm trying to accomplish a seamless transition from one interface to the other by temporarily plugging both interfaces into the same switch. Today, it appeared that I had a circular route, since after making the routing change, _both_ connections to the switch were required to pass traffic. Anyone seen this before/have suggestions for me?
