新手在防火墙这里。 。 我需要我的信任区访问互联网，但问题是我不能做到这一点。 到目前为止，从信任区域，我能够ping不信任区域中的IP，但是我不能ping信任区域或bgroup0内的IP。
我也可以在信任区内使用telnet到untrust区域。
这是我的configuration：

第二。 你的“不信任”的地址是192.168.200.x / 24 – 看起来像一个保留的IP。 你能ping通192.168.200.1的防火墙的不信任网关吗？ 你确定/ 24是正确的面具尺寸？ 你可以使用这些参数在“不信任”networking上设置一个系统，并连接到互联网吗？ 你能知道在默认网关之后下一跳的IP是什么吗？
第三。 您似乎没有将DNS设置为DHCP选项，所以您的DHCP客户端不会获得DNS服务器。 这是故意的吗？
第四。 除非来自“不信任”方的IP将启动与信任方的连接，否则您不需要策略2。 在策略1中，stream回信任端的stream量被隐含地允许为关联的。
第五。 除非有多个标记为“信任”的安全区域，否则不应使用“信任” – >“信任”规则。
第六。 你似乎正在通过不信任的界面进行所有的pipe理。 这可能是你想要的，但是对我来说倒退一些，允许不信任的networking访问你的pipe理。
