That's what it's defined to be. Changing that means fixing it everywhere. Also, as you get further from common setups, residential and soho routers tend to get flakier. Given that most users of such don't have hundreds of hosts and don't need two internal networks, a /23 in 192.168.0.0 qualifies as uncommon; it certainly gave me fits. I found that splitting the /24 into a pair of /25s worked better. > Additionally, your request probably should have gone to -net, not > -hackers. Yup. <mike
