Preface The company I work for uses a DrayTek router model that does not support WireGuard. By running WireGuard on a Debian VM instead, we gain: Performance decoupled from router hardware: the VM can scale (CPU/RAM/NIC), giving better crypto throughput. Clean, flexible routing: send only specific subnets (e.g., 192.168.0.0/24, 192.168.10.0/24) through the tunnel—no extra client-side commands. Keep personal internet as-is: regular web traffic does not exit via the company gateway, so external sites don’t see the company IP and your browsing isn’t slowed by the office uplink. Broad client compatibility: easy setup on Windows/macOS/Linux and mobile. Goal: Let external Windows...

Because the company policy only allows internal SMB access to a designated NAS server, this activity was deemed abnormal and suggested potential malware infection or misbehavior. In addition to the security concern, the excessive outbound SMB traffic also caused noticeable network performance degradation. Users reported that many websites became slow to load or failed to open entirely. Firewall inspection revealed that the abnormal SMB traffic was consuming significant bandwidth and disrupting WAN load-balancing behavior. Investigation and Malware Removal Upon...
