https://www.cloudflare.com/ips-v6 Open raw list Description
The IPv6 counterpart. Securing an origin server takes both files, otherwise the way in over IPv6 stays open. Seven entries that rarely change.
Integration
- Go to Firewall → pfBlockerNG → DNSBL → DNSBL Groups (or IP for IP lists).
- Click Add, give the group a name and add the URL below as source (Format: Auto).
- Save, then run Update → Force Reload.
https://www.cloudflare.com/ips-v6Address list per script
Fetch the list and import it into an address list called blocklist:
/tool fetch url="https://www.cloudflare.com/ips-v6" dst-path=blocklist.rsc
/import blocklist.rscIf the list is a plain text file with one address or CIDR per line, convert it first:
/tool fetch url="https://www.cloudflare.com/ips-v6" dst-path=blocklist.txt
:foreach line in=[/file get blocklist.txt contents] do={
/ip firewall address-list add list=blocklist address=$line comment="Cloudflare IPv6 ranges"
}Use the list in the firewall
/ip firewall filter add chain=forward src-address-list=blocklist action=drop comment="Cloudflare IPv6 ranges"
/ip firewall filter add chain=forward dst-address-list=blocklist action=drop comment="Cloudflare IPv6 ranges"Schedule the fetch with /system scheduler to keep the list current. Very large lists consume RAM, so check the available memory of your device first.
banIP (recommended)
- Install the package:
opkg update && opkg install banip luci-app-banip - Open LuCI → Services → banIP → Feeds and add a custom feed with the URL below.
