路由器Web服务器WAN访问


0

我有一个ISP提供的运行自定义固件的D-Link路由器。我正在尝试启用对WAN上路由器Web服务器的访问。虽然路由器确实在“ TCP / IP设置”>“ WAN接口”下提供了此选项,但该设置似乎无法使用,因为我无法使用公共IP访问Web服务器。

令人惊讶的是,其他功能(如在WAN上启用ICMP或SAMBA)也有效。启用后者后,将在WAN上打开端口445和139。iptables条目如下:(当然,IP已更改。)

#iptables -nL -v --line-numbers

如果未选中“通过WAN访问Web服务器”选项,则上面INPUT链中的规则#2更改为DROP,这意味着它确实起作用,但是由于某些原因,我无法从WAN访问Web服务器。请提出想法。

好的!因此,如果有人面临与我自己相同的问题,这是给他们的。

是我的ISP阻止了WAN接口上的端口80和23。当我更改端口时,它就像一个魅力!
