各位前辈好
小弟我最近有个需求是想把一台电脑当proxy
申请了中华的pppoe加上 中嘉宽带的固定ip
主机版的网卡接中华pppoe的线
PCIE的网卡接中嘉的线
eno1是主机版的网卡
enp4s0是pcie的tplink网卡
我在网络上查了一些文章自己试了很久还是搞不太懂
为什么其中一个对外可以通另一个就会不能通？
想请教各位前辈有没有什么解决方法？
提供资讯如下

当 proxy 跟两条出去的网络有什么关系吗？只留一个 default，另一个要指定网段

对你来说什么是通？对外连线是看路由表默认路由就只有一个外向内，本来就是怎么进怎么出了外向内走另一个出去，那就是用nat转发。跟两个对外连线也没什么关系外部通，两个ip都ping 的到如果ping 不到，那要看防火墙设定朋

你两个都要放上route 0.0.0.0/0

主要是有两个 default gateway 本来就是很混乱的一件事, 不如说说你想达成什么目的, 如何分配利用这两个 ip感觉接下来就会问多张 routing table 要怎么设, 或 namespace 要怎么用btw, 两个 pppoe 其实同一张网卡也可以作

哪里混乱 当metric死人喔 两个0.0.0.0/0才会通

放两个0.0.0.0/0 实际上会通的也只有一条只是那条通的断了之后一段时间会被丢到另一条去而已

这不是把两张网卡断开（disable ip forwarding)就好了
