Firewall Rules

This feature is available on sites with the WordPress.com Creator and Entrepreneur plans, and the legacy Pro plan. For sites on the free, Starter, and Explorer plans, upgrade your plan to access this feature.

In this guide

1. Inbound Firewall
2. Outbound Firewall

Inbound Firewall

Sites allow traffic over TCP ports 80 and 443 as well as support for uploading of files via TCP port 22 (SFTP). WordPress.com does not support, and will not add custom firewall rules to allow inbound traffic to your site or your site’s database/database server(s).

Outbound Firewall

Plugin-enabled sites allow outbound traffic to the following protocols and ports:

• TCP ports 465, 587 (SMTP)
• TCP ports 110, 995 (POP3)
• TCP ports 143, 993 (IMAP)
• TCP ports 80, 443 (HTTP, HTTPS)

All other outbound traffic is rejected and logged.
