[old stuff deleted] As I said in my prior response, redirects are commonly (though not always) ignored. Redirects are a way of spoofing, thus a security hole (even though they also have legitimate uses, as in your case). That XP rejects redirect instructions is quite reasonable. (Are you sure that your Linux client on the LAN is receiving and acting on the router's redirect message? You haven't said. In any case, if it is on network 192.169.250.0/24, and has default gateway 192.168.200.1, as your earlier message seemed to say, it has a more elaborate routing table than the WinXP host ... either a route to 192.168.200.0/24 or a static route to 192.168.200.1/32.) In any case, if this is the "point" of your query, is it not better made on a Windows XP list than a pair of Linux lists? (BTW, no one else has mentioned this, but cross-posting of this sort is usually considered discourteous.) Both Linux hosts on the LAN seem to be functioning correctly (at least as far as I can tell from your description). The only solution I can suggest is not to use the redirect trick to enable connectivity. Instead, give the WinXP host a proper routing table that tells it that it has a direct route to network 192.168.250.0/24. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" 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.linux-learn.org/faqs
