There are no rules for mangle and raw. 是否不同型号的Mikrotik router 的 default firewall rules 都不同的？我改了我以前的default rules 所以都不知是否一样？！ [i=s] 本帖最後由 角色 於 2019-3-3 22:22 編輯 [/i]
真的不知道，估计应该差不多。
如果你要reset，建议你要在router附近做，不然reset完你就连不回去你的router。
CCR series default是没有rules的。 [b]回復 [url=http://www.telecom-cafe.com/forum/redirect.php?goto=findpost&pid=46371&ptid=7383]3#[/url] [i]角色[/i] [/b]
我在官网找到以下 的default rules， 但是不了解跟楼上的default rules 功能上有什么不同？！
four basic firewall rules for mikrotik ros
[admin@MikroTik] /ip firewall filter> print
Flags: X - disabled, I - invalid, D - dynamic
0 ;;; default configuration
chain=input action=accept protocol=icmp
1 ;;; default configuration
chain=input action=accept connection-state=established
2 ;;; default configuration
chain=input action=accept connection-state=related
3 ;;; default configuration
chain=input action=drop in-interface=sfp1-gateway
4 ;;; default configuration
chain=input action=drop in-interface=ether1-gateway
5 ;;; default configuration
chain=input action=drop in-interface=ether2-gateway
[admin@MikroTik] 你上面的default settings是很久以前的rules，基本功能都是一样的，但是多了一些东西，如fasttrack and ipsec，还有网络优化。
