我需要添加一个新的路线10.10.10.0，现在我有这个：
# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 xx.xxx.xxx.1 0.0.0.0 UG 0 0 0 eth1 10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 yyy.yyy.yyy.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 zz.zzz.zzz.104 0.0.0.0 255.255.255.248 U 0 0 0 eth2 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 但从192.168.1.0我无法ping 10.10.10.0
你能给我一些提示吗？

xx.xxx.xxx.0和yy.yyy.yyy.104是公共ip
ip route add 10.10.10.0 255.255.255.0 gw <router address>
其中<router address>是既可以连接到客户端又可以连接到目标子网的路由器。
