-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, i have already had this problem with windows clients. It seems it's not a bug from your linux box, but only from the windows client, whose still have your old ip in cache. For my part, i don't know how to work around for this bug Le Lundi 29 Septembre 2003 10:23, lu a écrit : Hi, I have two lines that were masqueraded, one ADSL and another is ISDN for backup. When the line ADSL is broken I switch the line to ISDN. The problem is: when I use ping to test (ping -t from windows client), after the line was switched to ISDN, the source address was still that of ADSL instead of ISDN. But, when I stopped the ping from client for a while, all things went well. It seems a problem of cache. What is the work-around for it? At a moment I just down the ADSL interface. You can do this test with two lan interfaces. The Configuration is: iptables -t nat -A POSTROUTING -o hsb0 -j MASQUERADE # for ADSL iptables -t nat -A POSTROUTING -o ippp0 -j MASQUERADE # for ISDN default gw dev was hsb0 (ADSL) when ADSL was down then : route del default dev hsb0 route add default dev ippp0 Best regards, Jianliang Lu TieSse s.p.a Ivrea (to) Italy j.lu@xxxxxxxxxx luj@xxxxxxxxx http://www.tiesse.com - -- - - M.
