每次我的路由器连接到互联网时，我都会在路由器的防火墙日志中发现入侵警告。你能解释一下这是什么意思吗？是有人入侵了我的路由器，还是路由器断开了连接？
例如
Mar 11 14:15:11 kernel warning kernel: [fwlog] Intrusion -> SRC=85.102.133.241 DST=109.78.126.234
这是我的路由器防火墙完整日志

答案1
上网时随时受到端口扫描是完全正常的。这是不幸的事实。不过，除非您的服务暴露在互联网上，否则这不会带来任何风险。
您所看到的只是一条信息消息。不会造成任何损害，也不会尝试进行黑客攻击。
答案2
这不是入侵，只是意味着有人从外部扫描了你的路由器，试图找到一个开放的端口。我不会太担心这个 :)
通常在路由器上，进入您网络的端口（如果找不到更好的词，可以想象为“网关”）是关闭的。这些端口可以因各种原因（例如托管您自己的网站等）手动打开。
“黑客”喜欢扫描这些开放端口，试图找到进入您电脑的路径。如果您没有手动打开这些端口，那么应该没问题。如果您不确定，您可以运行自己的端口扫描这里亲自看看你是否有什么开放的:)
