你好，我的电脑有两个接口。这是我的 ifconfig 显示

问题是，在启动时，eth1 上的 10.250.xx 连接始终成为互联网访问的默认连接。这是我的路由显示
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 10.250.0.1 0.0.0.0 UG 100 0 0 eth1
default 192.168.108.1 0.0.0.0 UG 101 0 0 eth0
10.250.0.0 * 255.255.0.0 U 100 0 0 eth1
link-local * 255.255.0.0 U 1000 0 0 eth1
192.168.108.0 * 255.255.255.0 U 100 0 0 eth0
所以我有两个默认值，但 10.250 总是获得更好的指标。有没有办法改变这种情况，有没有办法简单地删除这个网关并只让 192.168.xx 作为网关？
