mikrotik ros设置3322的ddns

:global ednsuser "ixxxxn"
:global ednspass "yxxxx7"
:global ednshost "ixxxxn.3322.org"
:global ednsinterface "pppoe-out1"
:global members "\?system=dyndns"
:global status
:global status [/interface get [/interface find  name=$ednsinterface] running]

:if ($status!=false) do={
:global ednslastip [:resolve $ednshost]
:if ([ :typeof $ednslastip ] = nil ) do={ :global ednslastip "0" }
:global ednsiph [ /ip address get [/ip address find interface=$ednsinterface ] address ]
:global ednsip [:pick $ednsiph 0 [:find $ednsiph "/"]]
:global ednsstr "&hostname=$ednshost&myip=$ednsip"
:if ($ednslastip != $ednsip) do={
/tool fetch url="$members$ednsstr" mode=http user=$ednsuser password=$ednspass dst-path=$ednshost
:delay 4
:global result [/file get $ednshost contents]
:log info ($ednshost . " " .$result)
/file remove $ednshost ;
}
}

改变默认网关
/ip route set [/ip route find dst-address=0.0.0.0/0] gateway=xxx.xxx.xxx.xxx

定时重起
/system scheduler add name=reboot interval=24h start-time=11:59:00 on-event={/system reboot} disabled=no

定时执行
system scheduler add name=DDNSs interval=00:05:00 start-time=00:00:00 on-event=":execute DDNS"
