Routes and addresses are not the only problem. IIRC, older kernels did not automatically link an interface to the IP stack (it was not present in /proc/sys/net/ipv4/conf/) until you do something such as assign an IP address to it. > Though I guess it may > obstruct ICMP "TTL outlived" replies if the router itself has no address > to send with. Obviously, a router needs at least one non-loopback address in order to operate properly. If such an address is assigned to another interface, Linux can use it as a source address on the unnumbered interface. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
