你好，我正在尝试设置碘在dd-wrt在我的路由器上。我已经安装了它并设置了我的域。我目前的问题是，我的防火墙似乎阻止了端口 53？我想我应该通过 iptables 来解决这个问题。不太清楚该怎么做？
应该是这个吗？：
echo 1 > /prov/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o vlan2 -j MASQUERADE
iptables -A FORWARD -i vlan2 -o dns0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i dns0 -o vlan2 -j ACCEPT
执行 ifconfig vlan2 时，我的公网 IP 地址为。我还检查了端口是否在https://www.whatsmyip.org/port-scanner/并且显示已关闭，但据我所知我的 ISP 没有阻止端口 53
当尝试连接我的 Windows 客户端时（我当前已通过 VPN 连接到我的网络）：

I think 6485816 is too many. Setting interval to 1 to hopefully reduce SERVFAILs. But just ignore them if data still comes through. (Use -I1 next time on this network.)

Receiving too few answers. Will try to switch lazy mode off, but that may not always work any more. Start with -L0 next time on this network.
Server switched back to legacy mode.
有任何想法吗？
