Why Your WatchGuard VPN Needs a Blocklist

WatchGuard Firebox appliances are widely deployed in SMB and enterprise environments. If your Mobile VPN or IKEv2 port is exposed to the internet, bots are already probing it.

The Brute Force Problem

Automated scanners continuously sweep the internet for open VPN ports. Once found, they launch credential-stuffing attacks using leaked password databases. Your Firebox logs fill with failed authentication attempts from Mobile VPN with SSL, IKEv2, and L2TP connections, consuming resources and creating noise. Without proactive blocking, it is only a matter of time before a weak or reused credential is guessed.

Proactive Blocking with ThreatListPro + Blocked Sites

WatchGuard's Blocked Sites feature supports external feed URLs, allowing your Firebox to automatically download and enforce IP blocklists. ThreatListPro feeds directly into Blocked Sites as an external threat feed, blocking known VPN attackers at the firewall level. No failed logins, no log noise, no wasted resources. The list updates every 60 seconds and your Firebox pulls it on your configured schedule.

Blocked Sites Setup -- Step by Step

Add ThreatListPro as an external feed URL in WatchGuard Blocked Sites. Works with Firebox hardware, FireboxV, and WatchGuard Cloud.

01

Open Fireware Web UI or Policy Manager

Log in to your WatchGuard Firebox via Fireware Web UI at https://<firebox-ip>:8080 or connect through WatchGuard System Manager.

02

Get Your ThreatListPro Feed URL

Sign up at threatlistpro.com and copy your unique feed URL from the dashboard:
https://feed.threatlistpro.com/v1/edl/YOUR_API_KEY

03

Add External Feed to Blocked Sites

Navigate to Firewall > Blocked Sites. Click Add and select Feed URL. Paste the ThreatListPro URL and set the update interval to 60 minutes. Click Save to apply the configuration.

04

Configure Logging

Enable logging for blocked site connections under Logging & Notification. This lets you track blocked VPN brute force attempts in Traffic Monitor and review them in Log Manager or WatchGuard Dimension.

05

Verify Blocking

Check Traffic Monitor or Log Manager to confirm that IPs from ThreatListPro are being blocked. Look for denied connections matching IPs on the blocklist. You can also check Blocked Sites to verify the feed URL status shows as active.
