【问题描述】:
我有一个在虚拟化 Debian 8.5(Windows 10 下的 VirtualBox)下运行的测试游戏服务器;这台 Linux 机器在网络中有自己的 IP 地址。 游戏服务器使用端口 2106、7777 和 10241。我成功配置了我的盒子以使游戏服务器可从 WAN 使用,这 3 个端口被重定向到 Linux 机器 IP 192.168.1.70(测试从我的 Windows 机器 192.168.1.1 进行)。
我在 Windows 上做了一些 telnet 测试,比如:
telnet 192.168.1.70 2106 ==> Test OK
telnet 192.168.1.70 7777 ==> Test OK
telnet MY_PUBLIC_IP 2106 ==> Test OK
telnet MY_PUBLIC_IP 7777 ==> Test OK
telnet 192.168.1.70 10241 ==> Test KO !!
telnet MY_PUBLIC_IP 10241 ==> Test KO !!
同时,我 tcdump 来自 Linux 机器的数据包并拥有 2106 端口:
23:10:50.525372 IP 192.168.1.1.55598 > 192.168.1.70.2106: Flags [S], seq 2926133714, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0

对于 10241 端口:
23:06:38.490407 IP 192.168.1.1.55536 > 192.168.1.70.10241: Flags [S], seq 1465108966, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0

nmap -sT -O localhost 的结果:

还有 netstat -tulpn(删除了无用的端口):

tcp6 0 0 :::7777 :::* LISTEN 3811/java
我没有在 Linux 机器上配置防火墙(这是一台测试机器,不是实机),只有默认的 Debian IPtable。有人知道我可以做些什么来打开这个端口吗?
