Importing OpenDBL into MikroTik RouterOS IP Firewall Address Lists

MikroTik RouterOS supports automated HTTP/S list fetching into /ip firewall address-list using native RouterOS script tasks and System Scheduler.

1

Create RouterOS Fetch & Parse Script

In WinBox or WebFig, navigate to System > Scripts and add a new script named FetchOpenDBL.

/tool fetch url="https://opendbl.net/lists/ipsum.list" mode=https dst-path=opendbl.txt
:foreach line in=[:toarray [/file get opendbl.txt content]] do={
    :if ([:len $line] > 0) do={
        /ip firewall address-list add list=OpenDBL address=$line timeout=1d comment="OpenDBL Threat Feed"
    }
}
2

Schedule Periodic List Refresh

Navigate to System > Scheduler and add a scheduled task to execute FetchOpenDBL every 15 to 30 minutes.

3

Apply Drop Filter Rule

In IP > Firewall > Filter Rules, create a rule with action=drop and set src-address-list=OpenDBL or dst-address-list=OpenDBL on your WAN interface.
