Deep Security 11.3 has reached end of support. Use the version selector (above) to see more recent versions of the Help Center.
Port numbers, URLs, and IP addresses
Deep Security default port numbers, URLs, IP addresses, and protocols are listed in the sections below. If a port, URL or IP address is configurable, a link is provided to the relevant configuration page.
If your network uses a proxy or loadbalancer, you can configure Deep Security to use it instead of the default ports and URLs listed on this page. For details, see Proxy settings
In addition to the ports on this page, Deep Security uses ephemeral ports when opening a socket (source port). Under rare circumstances these may be blocked, causing connectivity issues. For details, see Activation Failed - Blocked port.

| Deep Security Relay listen ports |
4123 should not be listening to connections from other computers, and you don't need to configure it in network firewall policies. But if you have firewall software (such as Windows Firewall or iptables) on the manager's server itself, verify that it does not block this connection to itself. Also verify that other applications do not use the same port (a port conflict). |
