RouterOS firewall address list synchronization to CrowdSec Blocklist Mirror

• DockerHub crowdsec
• DockerHub blocklist-mirror
• Docs Blocklist mirror

Configure Blocklist Mirror or use your own list of IP addresses (need HTTP format output list)

config.yml

blocklists:
  format: plain_text

Create certifcates

/certificate
add name=CA-Template common-name=CAtemp key-usage=key-cert-sign,crl-sign
add name=Server common-name=server
add name=Client common-name=client

Certificates should be signed. Change your RouterOS host address

/certificate
sign CA-Template
sign Client     
sign Server ca-crl-host=192.168.88.1 name=ServerCA

Enable API-SSL. Change api access address

/ip service
set api-ssl address=192.168.88.0/24 certificate=ServerCA

change .env file variables

cp .env.exmaple .env
nano .env

build

docker build . -t mikroseclist:latest

or use github image

docker pull ghcr.io/akmalovaa/mikroseclist:latest

using docker compose - compose.yaml

services:
  mikroseclist:
    image: ghcr.io/akmalovaa/mikroseclist:latest
    container_name: mikroseclist
    command: ["python", "-m", "mikroseclist"]
    environment:
      MIKROTIK_HOST: ${MIKROTIK_HOST:-'192.168.88.1'}
      MIKROTIK_USER: ${MIKROTIK_USER:-'admin'}
      MIKROTIK_PASSWORD: ${MIKROTIK_PASSWORD:-'password'}
      BLOCKLIST_URL: 'http://blocklist.example.com:41412/security/blocklist?ipv4only'
      SYNC_INTERVAL_MIN: 30
    restart: unless-stopped

change environment variables and run:

docker-compose up -d

After first syncing сhange Mikrotik Firewall Rules

/ip firewall filter
add action=accept chain=input src-address-list=access # access list optional
add action=drop chain=input in-interface=ether1 src-address-list=block
add action=drop chain=forward in-interface=ether1 src-address-list=block

You can override this variables in the .env file

You can use default CrowdSec Blocklist mirror format without mikroseclist service:

Actual IP addresses will already be in the blocked list

CrowdSec Blocklist mirror

Allows you to use a list of IP addresses to add

config.yml

blocklists:
  format: mikrotik

Output lines for mikrotik, format is /ip|/ipv6 firewall address-list add list={list_name} address={ip} comment="{scenario} for {duration}"

The list of IP addresses is very large ~ 25,000, when updated in this way, all addresses are deleted and added again. It's pointless to do this every time you update.

This service mikroseclist only allows you to edit changes. Add and delete only new addresses, not the entire list
