windows-7 – W7路由 – 流量不会进入默认网关

前端之家收集整理的这篇文章主要介绍了windows-7 – W7路由 – 流量不会进入默认网关前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我有一个非常奇怪的 Windows 7 IPv4路由问题,我无法深究.

该问题的摘要是默认网关设置为192.168.254.253,但它实际上使用默认网关192.168.254.254.

这是一个网络图:

这是最近(几周前)转换的光纤站点,原有的2条DSL线路仍然连接并运行.使用光纤线路安装了Untangle(防火墙).

最后,从第二个工作站执行tracert会产生预期结果:

C:\Users\administrator>tracert -d www.bbc.co.uk

Tracing route to www.bbc.net.uk [212.58.244.67]
over a maximum of 30 hops:

  8     2 ms     2 ms     2 ms  195.66.224.103

正如预期的那样,它通过.253路由,第二跳是Juniper NTU的内部接口.

我还没有检查过交通.特别是,我打算寻找ICMP重定向,虽然为什么会有ICMP重定向根本不明智?

.254曾经是光纤安装前的默认网关.

有任何想法吗?对我来说没有意义为什么应该有这个路由问题:(

Draytek双WAN路由器重新启动,PC重新启动. PC已禁用网络,然后重新启用. Windows失去情节时的所有标准内容.

希望有人认识到这些症状!

PS:很抱歉很长的帖子,但我不想留下一些可能相关的内容.

PPS:此工作站或任何其他工作站上没有涉及iSCSI,因此Windows 7 routing traffic through the gateway for local addresses不是问题.

当有问题的工作站获得一个新的,不同的IP地址时(我怀疑原始租约已过期),此问题已自行修复.

除了不同的IP地址,“ipconfig / allcompartments / all”输出是相同的,“route print”是相同的,我查看的其他所有内容都是相同的.

回想起来,我认为Windows 7发布和版本有问题.更新代码实际上似乎没有正确或完全重置TCP堆栈.我在其他场合指出,如果你在Windows网络上启动一个新的DHCP服务器,那么工作站似乎坚持原始的DHCP服务器并且不进行全面搜索,即首先找到网络上的DHCP服务器是.

如果我将来遇到类似的情况,我会首先尝试摆弄DHCP.

如果您正在努力解决相同的问题,可以检查租约时间,然后将日期/时间更改为未来,以便工作站到期?或者,您可以从服务器到期租约?

如果你找到一个好的工作方法,请在这里添加一个答案.
