 我这边使用的方案与其类似：使用刷有openwrt的路由器，通过ua3f和bashclash来完成躲避校园网的检测
 
+首先在
+
 lca也有过部署经验，一次为了不重复造轮子，请先查看他的博客地址：https://luckylca.github.io/2025/08/29/csust-network-crack/
 
+ssh连上路由器后
+
+```bash
+opkg print-architecture
+# 检查路由器架构，安装对应ua3f ipk文件
+```
+
+[猴子也能看懂的 UA3F 使用教程](https://sunbk201public.notion.site/UA3F-2a21f32cbb4b80669e04ec1f053d0333)
+基本上跟着这个走安装ua3f就没有问题
+
+```bash
+export url='https://fastly.jsdelivr.net/gh/juewuy/ShellCrash@master' && wget -q --no-check-certificate -O /tmp/install.sh $url/install.sh  && sh /tmp/install.sh && source /etc/profile &> /dev/null
+# 安装bashcrash
+```
 
 
 其中需要注意的是在配置统一useragent 头的地方，在给bashclash传配置的config文件时，之前的配置文件已经更新了，详见：
 
 https://github.com/SunBK201/UA3F/blob/master/docs/clash/Clash.md
 
+```bash
+nft add rule ip mangle POSTROUTING oif br-lan ip protocol ip ip ttl set 128
+```
+
+
+
+```bash
+# 备份原配置
+cp /etc/firewall.user /etc/firewall.user.backup 2>/dev/null
+
+# 添加TTL规则到防火墙用户规则
+cat >> /etc/firewall.user << 'EOF'
+
+# === TTL设置规则（无线和有线）===
+# 清理并重新设置TTL规则
+nft delete table ip mangle 2>/dev/null
+nft add table ip mangle
+nft add chain ip mangle POSTROUTING { type filter hook postrouting priority mangle; policy accept; }
+nft add rule ip mangle POSTROUTING oif "br-lan" ip ttl set 128
+nft add rule ip mangle POSTROUTING oif "phy0-ap0" ip ttl set 128
+nft add rule ip mangle POSTROUTING oif "phy1-ap0" ip ttl set 128
+EOF
+
+# 重启防火墙
+/etc/init.d/firewall restart
+```
+
+
+
 就同样的修改一下代理的配置即可
