I've encountered the following problem on two different servers (3.1-R and 3.3-R): We've a class B network with proxy arp which I don't use (endless arp moved ... messages within syslog - any idea how to suppress them?); both machines use netmask 255.255.255.0 and a default router to communicate with the world outside the subnet. From time to time, one or two or very few machines outside the class C subnet but inside the class B net are not reachable - traceroute doesn't show any(!) successful hop, and `netstat -r' or `arp -a' don't show anything special with that machines. I will be able to traceroute to `a.b.c.n-1' but not to `a.b.c.n' in such a situation. Adding a static route to the machine, tracing the route and then deleting the static route will be a workaround - the system will stay reachable after that sequence. Any idea why the whole thing happens?
