我正在尝试找出问题可能出在我的配置中。大约一个月前，我们通过 Juniper SSG5 轻松通过我们的提供商获得 100 的上行速度和 50 的下行速度。几周前开始情况发生了变化。如果我直接插入电缆调制解调器，一切都很好，我可以获得全速。如果我插入 netscreen，它会下降到大约 20 - 25 的下行速度和 20 - 25 的上行速度。我已经更换了电缆以及 netscreen 本身。唯一剩下的事情似乎就是配置了。

有谁发现有什么明显的东西吗？
答案1
尝试使用小型 SOHO 路由器（例如 dlink 或 linksys）。SSG5 是入门级防火墙，在大型 ISP 链路上，数据包检查服务可以杀死防火墙，而 SOHO 路由器则不进行任何检查，就像您的 PC 一样。
如果测试成功，则需要升级路由器。
