我有一台运行在虚拟化Debian 8.5(VirtualBox在Windows 10下)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,使游戏服务器可以从WAN使用,这3个端口被重定向到Linux机器IP 192.168.1.70(测试是从我的Windows机器192.168.1.1进行的)。无法在Debian 8.5下打开端口10241
我从Windows取得了一定的telnet测试,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 !!
与此同时,我tcdump从Linux机器的数据包和对端口2106:
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

而对于端口10241:
结果的nmap -sT -O localhost

我没有防火墙配置到Linux机器(这是一个测试机器,而不是活机),只有默认的Debian的iptable。有人知道我可以做些什么来打开这个端口吗?
第一个命令没有任何回报,第二个发送但没有任何反应 –
任何其他的想法? –
