Hi, I used to use configuration like "up ip route add 0.0.0.0/0 via a.b.c.d dev eth0" in /etc/network/interfaces to do this. But today, in debian doc (http://www.debian.org/doc/manuals/reference/ch05.en.html 5.5.14), I found that there is a /etc/network/routes to do this. Well, I cannot find more information about it. Anyone could help giving me a clue? Thanks. -- 竹密岂妨流水过 山高哪阻野云飞
