R4S在电脑开启比特彗星后会越来越卡，过几分钟时间恢复

[llzzll]

不管是不是在下载，只要开着就会，3月24晚上编译的固件。 卡的期间连luci界面都进不去，ssh也进不去。 开启了SFE和fullconenat，ipv6helper，SSRP

[TXH201622]

两个方法 1.关闭nat1 2.将BT彗星的UDP发包数从1000改为100

[coolsnowwolf]

比特彗星 的 Bug，不断的发送 ARP 更新表，把路由器 ARP Table 充满了

比特彗星 的 Bug，不断的发送 ARP 更新表，把路由器 ARP Table 充满了

那解决方案就是改udp发包数或者换fullcone吗？还有就是请教一下为什么这么明显的bug在其他路由器上没有见过呢？

貌似大部分路由器默认都没有FULLCONE NAT，尤其是三剑客。
