she*_*iel 6 vpn routing proxy juniper
当从家里连接到公司 VPN 时，所有流量都被重定向到公司代理，从而有效地阻止我在家时想自由使用的站点，并减慢对外部站点的访问。我怎样才能撤销这种情况？
我在问与此处相同的问题，在 Cisco VPN 上避免公司阻止的 URL，但我的 VPN 客户端是瞻博网络，操作系统是 windows7。没有对我有用的答案： - 瞻博网络客户端没有“在远程网络上使用默认网关”配置 - 我无法在 win7 的控制面板上找到设置（我可以找到连接，而不是 IpV4 = > 属性 => 高级 => Ip 设置，但没有类似于“在远程网络上使用默认网关”
有趣的是，同样的 vpn 客户端不会通过我的另一台运行 WinXP 的计算机上的公司代理强制流量

绝对有可能。我编写了一个脚本，为我知道不需要进入我的公司网络的所有 IP 范围设置到我的家庭网关的静态路由。然后它启动网络连接，然后更新Instantproxy.pac文件。（注意我的公司网络在 136.xxx）
基本想法如下 - 祝你好运：

大概。没有足够的信息来给出全面的具体答案。
当接口（物理或逻辑）激活和停用时，会添加和删除路由。接口激活操作添加路由，并且（通常）优先使用最近添加的路由。当您登录 VPN 时可能会发生的情况是创建/激活新的逻辑网络接口，并且路由表更新为默认使用它。假设 Juniper 客户端创建了一个隧道接口，并且没有添加本地主机防火墙（并且您没有违反公司策略 - 这可能是故意的），您应该能够
您链接到的问题中的MSKB 140859提供了很多理论，但没有提供太多实践。
如果您了解该理论，那么跑步netsh interface show interface以及route print连接之前和之后应该会很有用。
