How enable DDNS in firewall rules

Hi,

I want to use DDNS but I realised that with current config I can’t connect. If I disable the drop rule it works perfect.
How can I add a rule to allow DDNS?. Or modify this.

 0 XI  ;;; place hotspot rules here
      chain=unused-hs-chain action=passthrough log=no log-prefix="" 

 1    ;;; Established
      chain=input action=accept connection-state=established log=no log-prefix="" 

 2    ;;; Related
      chain=input action=accept connection-state="" log=no log-prefix="" 

 3    ;;; Management
      chain=input action=accept src-address-list=management log=no log-prefix="" 

 4    ;;; ICMP
      chain=input action=accept protocol=icmp log=no log-prefix="" 

 5    ;;; DHCP
      chain=input action=accept protocol=udp dst-port=67-68 log=no log-prefix="" 

 6    ;;; PPTP access
      chain=input action=accept protocol=gre log=no log-prefix="" 

 7    ;;; PPTP access
      chain=input action=accept protocol=tcp dst-port=1723 log=no log-prefix="" 

 8    ;;; Drop
      chain=input action=drop log=no log-prefix=""

I think active DDNS from Ip, Cloud
And select true on DDNS after some time you see code that meaning DDNS.

Hi.
I don’t undestand. I can enable DDNS in IP → Cloud.
But I have problems with firewall rules. With current config I can’t use DDNS and I don’t want to disable ‘‘Drop’’ rule since its risky.

Whats the rule you used in firewall for ddns

I dont have any rule specifically for DDNS. Which one should I add?

6

I think there is now rule add in filter of firewall.
Only active from ip cloud and save the code for ddns

Maybe you can use this in firewall filter rules

;;; Cloud IP
chain=input action=accept protocol=udp in-interface=WAN src-port=15252 log=no log-prefix=“”
