SWIPE Application Cannot Connect to SmartZone (SZ) Through a Firewall

Summary

This article describes the firewall port requirements for communication between the SWIPE application and SmartZone (SZ). Connectivity issues can occur when the required ports are not permitted through a firewall. This article outlines the symptoms, root cause, troubleshooting steps, and required firewall configuration.

Question

Why can't the SWIPE application connect to SmartZone (SZ) when only port 8443 is open on the firewall?

Customer Environment

SmartZone (SZ) controller SWIPE application 2.0 or later Firewall between the SWIPE application and SZ Remote administration or monitoring deployment

Symptoms

SWIPE application cannot connect to SZ

Host is reported as unreachable

Remote management functions are unavailable

Root Cause

The firewall is blocking one or more ports required for communication between the SWIPE application and SZ. For SZ 3.0 and later, TCP port 7443 is required in addition to TCP port 8443. Communication may fail if either port is blocked.

Troubleshooting Steps

Verify the SZ software version.
Confirm that TCP port 8443 is open between the SWIPE application and SZ.
If running SZ 3.0 or later, verify that TCP port 7443 is also open.
Review firewall rules and access control lists (ACLs) for blocked traffic.
Test connectivity to ports 8443 and 7443 from the client network.
Retest connectivity using the SWIPE application.

Workaround

If the SWIPE application and SZ are located on the same network and communication does not traverse the firewall, the application may connect successfully without modifying firewall policies.

Resolution

Configure the firewall to allow the required TCP ports between the SWIPE application and SmartZone (SZ).

SZ Version	Required Port(s)	Protocol	Purpose
SZ 2.5	8443	TCP	SWIPE login and communication
SZ 3.0 and later	8443 and 7443	TCP	SWIPE login and communication

Note: For SZ 3.0 and later releases, TCP port 7443 is required in addition to TCP port 8443.
