可以从外部网络访问我的 DNS 主机,但不能在 LAN 内访问

可以从外部网络访问我的 DNS 主机,但不能在 LAN 内访问

基本上,如标题所示。这是 Advanced Tomato 固件。 NAT 环回已配置。目前设置为“仅转发”(还有一个端口转发规则)。但是,尝试设置“全部”,仍然没有结果。

iptables当前“仅转发”方法的 NAT:

iptables -n -L -v -t nat
Chain PREROUTING (policy ACCEPT 873 packets, 164K bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain INPUT (policy ACCEPT 77 packets, 15650 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)

Chain POSTROUTING (policy ACCEPT 158 packets, 19846 bytes)

iptables针对“全部”方法的 NAT:

iptables -n -L -v -t nat

NAT target设置为“MASQUERADE”。但是,我也尝试了“SNAT”,但没有成功。

99.99.99.99 - 是我的屏蔽外部白色(静态)IP 地址

可能是什么问题呢?
