(when I ping > from windows I get a response, so the system isn't down.) That is because 207.172.3.8 is not directly connected. By speficying a route entry with -iface you specify it is directly connected. That is the reason you can now reach the 10.*hosts. The problem with the 207.172.3.* hosts exists because your routing table expects the 207.172.3.* range to be directly connected. So either you have to make them apear directly connected, or you must say that they are not directly connected. The first can be doe by having your gateway do proxy arp, or by manually setting arp entries on your host (for all 207.172.3.* hosts, do arp -s host MAC, where MAC is the mac address of your gateway). I don't know how to do the second one, except for adding single host routes for each host, i.e.: route add host-ip-address gateway-ip-address. -Guido To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
