子网互通开关无法启用

[acnixuil]

固件：imm23.05 防火墙：fw4 勾选子网互通后，使用手机数据可以正常访问其他网段的数据，但本地的设备就无法做到，手动执行tailscale down和tailscale up一次后，子网互通又正常了

问题同 #22 ，可能由于路由未即时生效，本机测试环境下同样无法复现。

临时解决方案：在勾选选择其他的节点名称作为出口节点使用 以及 子网互通等涉及路由相互操作后，通过基础设置的启用开关对tailscale进行关闭和再次启动。

该问题可能由于插件冲突导致，目前观察到的冲突有：

1. OpenClash（dns fight导致MagicDNS无法正常使用；路由表无法正常生效）。改用mihomo后问题解决。
2. passwall2 开启路由器本机代理后无法正常打洞。见#19
3. iptables 或 iptables-nft等，当前OpenWrt主线已默认使用nftables，同时使用iptables规则可能导致防火墙设置冲突。

由于插件冲突引起问题将不做修复，请自行取舍。本插件已尽量仅使用uci命令对路由表、防火墙、网络接口进行操作以规避冲突。

使用的插件只有mihomotproxy，已在规则添加tailscale相关域名走direct。 1.尝试使用临时方案，手动关闭-打开开关，还是无法访问。 2.关闭除tailscale以外的插件，正常配置好，勾选子网互通后重启，还是无法访问。

日志太长，我截取一段

我尝试了你仓库最新x86-64固件问题依旧无法复现，路由、子网互通设置可实时生效。
