[WireGuard interface issue]

Attention Zenarmor Users!

OPNsense 24.7 users may be experiencing the following issues. The Zenarmor team is currently working on resolving them, and they will be fixed with the upcoming release, 1.17.6. This release will be shipped at the beginning of next week. We advise users not to upgrade their OPNsense platform to the 24.7 version until we make our next announcement for safe operation.

Thank you for your understanding and patience.

1. WireGuard interface issue. Zenarmor engine can not report and apply policies to the WireGuard interface. There is a workaround solution for this issue by OPNsense. Please check the following forum link

Dear Zenarmor Users,

Some of our users have reported compatibility issues with filtering WireGuard VPN traffic on OPNsense 24.7. We are currently investigating the issue. If you are using Zenarmor to protect WireGuard VPN interfaces (kernel mode), we advise you not to upgrade your OPNsense platform to the latest version until we make our next announcement for safe operation.

Dear Zenarmor Users,

The OPNsense upgrade process for major versions does not involve downloading third-party repositories or packages, such as Zenarmor. Instead, it updates the self-contained OPNsense ecosystem to prevent overlap errors and dependency mismatches between OPNsense and third-party repositories. 

Consequently, Zenarmor users who upgrade their OPNsense platforms to the latest version, 24.7, need to install Zenarmor packages that are compatible with the new operating system, FreeBSD 14.1, by running the update. 

In simpler terms, Zenarmor users should complete Zenarmor updates by immediately installing updates after the major OPNsense 24.7 upgrade is finished.

If you encounter any issues during the OPNsense 24.7 upgrade, feel free to contact the Zenarmor team for assistance.

Best Regards

Dear Beloved Zenarmor Users,
A SYN flood interrupts a web service using a TCP/IP handshake vulnerability. In the world of cyber threats, the TCP SYN Flood stands out as a particularly malicious type of denial-of-service (DoS) attack. By manipulating the protocols that govern internet communication, attackers can flood servers, rendering them unavailable to genuine queries.
This article covers the SYN flood attack. Explore the complexities of TCP SYN Flood, a common denial-of-service attack. Learn about its processes, the hazards it may bring to computer networks, and the tactics used to combat such attacks.
