How to Configure the Firewall in the Webuzo Admin Panel

A firewall is your server’s front-line defence, deciding which traffic is allowed in and which is turned away. On a Webuzo VPS or dedicated server, configuring the firewall correctly keeps your services reachable while shutting the door on attackers. This is an admin-level task.

Open the firewall settings

Log in to the Webuzo Admin Panel.
Open the Security or Firewall section.
From here you can enable the firewall and manage its rules.

Ports you must keep open

Blocking the wrong port can lock you out or take services offline, so make sure these stay open:

2002–2005 — the Webuzo Enduser and Admin panels.
80 and 443 — your websites (HTTP and HTTPS).
22 — SSH access.
21 — FTP.
25, 465, 587, 993, 995 — email sending and receiving.
53 — DNS, if your server runs it.

Blocking and allowing addresses

Use the firewall to block IPs behaving badly, and to whitelist trusted ones such as your own office. For blocking a single nuisance visitor at the site level instead, see blocking an IP address in Webuzo.

Frequently asked questions

I locked myself out after changing the firewall.

Connect through your provider’s console (VNC/KVM) to fix the rule, or contact support. This is why whitelisting your own IP first is so important.

Do I need a firewall if I already block IPs in the panel?

Yes — a server firewall protects every service, not just websites. IP blocking in the Enduser Panel only covers web traffic for one account.

Which firewall does Webuzo use?

Webuzo manages server firewall rules for you through the panel. For advanced setups you can also work with the underlying firewall over SSH, though most needs are met from the Admin Panel.
