Using these options can reduce high I/O wait and prevent the server from becoming slow while backups are running.https://www.virtualizor.com/docs/admin/backup-plans/#process-priority]]> Sun, 21 Dec 2025 06:32:09 GMT https://www.softaculous.com/board/index.php?tid=20606&tpg=1#p60445 https://www.softaculous.com/board/index.php?tid=20606&tpg=1#p60444
How do you perform backups on Virtualizor? I am experiencing a high I/O wait issue on the server when the backup runs. I'm using two types of disks: LVM and a raw-based file system. My remote location is in the same data center, but I am experiencing slow I/O, and sometimes Virtualizor even gets stuck.]]> Sun, 21 Dec 2025 05:33:18 GMT https://www.softaculous.com/board/index.php?tid=20606&tpg=1#p60444 https://www.softaculous.com/board/index.php?tid=20547&tpg=1#p60369
is your local IP internal?
also, do you have an internal/local IP pool?

if the pool is added, then you can add the second bridge in the pool as a VLAN.

Or if the IPs are internal, then you can set it up by our guide below

## **1. Understand the Setup**

WHMCS itself doesn’t directly provide firewall management, but you can integrate it with:

* **Server-level firewalls** (CSF, ConfigServer, iptables, UFW) via WHMCS modules or API
* **Cloud firewalls** (like Cloudflare, AWS Security Groups, or cPanel/WHM firewall) via API integrations

The goal: give your clients a **user-friendly interface** to configure basic firewall rules (allow/deny IPs, block ports, enable/disable services) without logging into the server.

---

## **2. Create a Client Firewall Module**

1. **Decide on firewall type:**

  * For Linux servers: CSF (ConfigServer Security & Firewall) is popular.
  * For cloud servers: APIs (Cloudflare, AWS, DigitalOcean, etc.) can handle rule changes.

2. **Develop a WHMCS module:**

  * WHMCS modules can use the **Server API** or a **custom PHP script**.
  * Provide functions like:

    * `createRule($clientId, $rule)`
    * `deleteRule($clientId, $ruleId)`
    * `listRules($clientId)`

3. **Add client area interface:**

  * Let clients **add/remove rules**, view blocked/allowed IPs, and see firewall status.
  * Use WHMCS hooks to fetch real-time server data.

---

## **3. Server-Side Configuration**

* **CSF / iptables / UFW:**

  * Ensure the firewall supports dynamic rule updates via scripts or API.
  * Configure a **dedicated API user or key** for WHMCS to authenticate.
* **Cloud firewalls:**

  * Ensure your API credentials have proper permissions (read/write).
  * Rate-limit API calls to avoid hitting provider limits.

---

## **4. Security Considerations**

* **Authentication:** Only allow clients to modify **their own rules**.
* **Input validation:** Make sure IPs, ports, and protocols are sanitized.
* **Logging:** Keep a record of all client changes for auditing.
* **Limits:** Avoid giving unlimited access—e.g., max number of rules per client.

---

## **5. Workflow Example for a Client**

1. Client logs into WHMCS → Client Area → Firewall Settings.
2. Adds a rule: allow 123.123.123.123 to port 22.
3. WHMCS module calls server API → updates firewall dynamically.
4. Rule shows as active in the client area.
5. Client can later remove or disable the rule; WHMCS syncs the change with the server.

---

## **6. Optional Enhancements**

* **Real-time status:** Show blocked/allowed traffic logs.
* **Templates:** Predefined rules for common services (SSH, HTTP, FTP).
* **Notifications:** Email clients when their firewall blocks suspicious traffic.
* **Tiered access:** Allow different firewall levels depending on client plan.
