Fastnet Technical Notice: Draytek Router Connectivity Issues

2025-03-24 10:01:03
We are aware of an ongoing issue affecting Draytek routers, causing connectivity problems for users across multiple ISP’s nationally. This appears to be triggered by a targeted attack exploiting vulnerabilities in certain Draytek router software versions. Whilst we do not ordinarily supply these, we know that some customers choose to use them on their connections, either to us or other providers
Recommended Actions:
1. Software Update: We strongly recommend upgrading your Draytek router to the latest firmware, as this is expected to resolve the issue.
2. Security Adjustments: If the software update does not resolve the issue, ensure that remote access to the router is disabled and that any VPN services — particularly SSL VPN on port 443 — are turned off.
3. Hardware Replacement: If the issue persists despite these measures, replacing the router with a different model may be the most effective solution.
We encourage affected users to take immediate action to mitigate disruptions. If further assistance is required, please contact our support team.
