我已经设置了具有三个接口的小型服务器/小型服务器。一个接口通向内部网络,并在路由表rt1中拥有一条默认路由。另一个接口连接到Fritz!Box并连接到Internet,并且在路由表rt2中也具有默认路由。
我已经建立了两个默认网关(表rt1和rt2),现在我想在某个接口(eth0.103)上ping互联网中的某些内容,这会导致Fritz!Box(和互联网),或者即使在这两个接口上都可以,但这不起作用,尽管traceroute甚至SSH连接都在此接口上运行。我的意思是,我什至可以从外部或通过Fritz!Box /互联网与该盒子(eth0.103)联系/连接。另外,在eth0.101上,没有路由或ping操作。
Fritz!Box的地址为192.168.178.1,并直接连接eth0.103(192.168.178.20)。

我无法弄清楚,如果我对那些网关或路由规则/表做错了。另外,我觉得很奇怪,我可以通过Fritz!Box的公共IP地址连接到服务器,而无法从ping通。预先谢谢大家。
答案 0 :(得分:0)
好的,在Linux站点上进行了大量的搜索和阅读,在Stack Overflow上,我找到了解决方案。
路由表很好,但是不将默认网关传输到主表。因此,我无法ping或无法完成任何操作,但traceroute仍在工作。甚至静态路由也有效。
因此,我在/ etc / network / interfaces中添加了这两行(带有度量值),现在两个路由表的默认网关都传输到了主路由表。
