破解 DD-WRT 连接数限制(最大端口数)

其实也不算是破解,只是将最大连接数设置的大一点。默认 DD-WRT 的设置是 4096,对于一般使用 ADSL 1M 已经足够了。

登录入 Web 管理界面,进入 Administration -> Commands。输入如下命令,并保存为启动脚本。

nvram set ip_conntrack_max=65536
echo 65536 > /proc/sys/net/ipv4/netfilter/ip_conntrack_max

其实连接数也不是越大越好,最大值为 65536,可以参照 1M -> 2048,2M -> 4096。
还有其实厂商默认的固件其实应该是最稳定的,DD-WRT 主要追求的是多功能性。所以不折腾的话就用默认固件就好啦,也没有连接数这茶事。
