Okay, I'll show my ignorance and ask... the Documentation for arp_filter says source routing must be used. Is there some flag I'm missing, or a way to avoid having a rule per address, or is the 8 bit rule number larger in 2.6, or ??? Or is having a lot of IPs on one machine not an imaginable case? -- bill davidsen CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
