Ports scanned or used by Lansweeper

[Lansweeper]

This page provides an overview of the ports scanned by Lansweeper, including ports used for internal communication between Lansweeper components and ports used for communication with scanned devices.

Below is an overview of ports scanned by Lansweeper on client machines and ports used for internal communication between Lansweeper components.

To check the status of your ports, check out the pro tip Ports Status.

• Lansweeper web console access
  HTTP port specified in the Lansweeper installer
  HTTPS port specified in the Lansweeper installer, when the default web server (IIS Express) is used. When using the alternate IIS web server, an HTTPS port must be configured directly in IIS Manager.
• Lansweeper service and web console to Microsoft SQL Server database
  Port: 1433/TCP and possibly other SQL Server related ports
  Which ports must be opened on the machine hosting your SQL Server instance depends on how your instance is configured. Port 1433 is a common port used for SQL Server traffic, but additional ports may need to be opened as well. Please review this Microsoft knowledge base article for detailed information on how to allow SQL Server traffic through a firewall.
• Lansweeper service to Active Directory domain controllers
  Port: 389/TCP (LDAP) or another LDAP(S) port of your choice
  Port: 88 (if Kerberos is enabled or enforced)
• Lansweeper service to scanned Windows computers
  Port: 135/TCP (DCOM to establish the initial WMI session with the computer)
  Port: 139/TCP (NetBIOS Session Service)
  Port: 445/TCP (SMB)
  Random ports in the 1025-5000 or 49152-65535 range (to send the WMI data)
  By default, Windows sends WMI data over random ports, as explained in this Microsoft knowledge base article. There are three options to ensure the data stream: 
  

  1. Configure your firewalls to allow all WMI traffic. Windows Firewall includes a remote administration exception that you can enable to allow WMI traffic, as explained in this knowledge base article. For third-party firewalls, consult your firewall's documentation.
  2. Configure a fixed WMI port and allow traffic through that port.
  3. If you are unable to allow WMI traffic through your firewalls, scan your computers with the LsAgent or LsPush scanning agent instead, which does not require firewall reconfiguration.
• Lansweeper service to scanned Linux, Unix and Mac computers
  Port: 22/TCP (SSH) or a custom SSH port of your choice
• Lansweeper service to scanned VMware servers
  Port: 443/TCP (HTTPS)
• Lansweeper service to scanned network devices
  ICMP Ping
  Port: 21/TCP (FTP)
  Port: 22/TCP (SSH) or a custom SSH port of your choice
  Port: 23/TCP (Telnet)
  Port: 25/TCP (SMTP)
  Port: 80/TCP (HTTP)
  Port: 135/TCP (EPMAP)
  Port: 137/UDP (NetBIOS Name Service)
  Port: 139/TCP (NetBIOS Session Service)
  Port: 161 (SNMP)
  Port: 443/TCP (HTTPS)
  Port: 445/TCP (SMB)
  Port: 1400/TCP (Sonos devices HTTP)
  Port: 1900/TCP (SSDP, UPnP)
  Port: 1900/UDP (SSDP, UPnP)
  Port: 5060 (SIP) or a custom SIP port of your choice
  Port: 5353/TCP (mDNS, DNS-SD)
  Port: 5353/UDP (mDNS, Bonjour, DNS-SD)
  Port: 5985/TCP (without SSL; WinRM HTTPS for Windows cluster log scanning and Hyper-V log scanning)
  Port: 5986/TCP (with SSL; WinRM HTTPS for Windows cluster log scanning and Hyper-V log scanning)
  Port: 8008/TCP (Chromecast)
  Port: 8080/TCP (HTTP)
  Port: 8443/TCP (HTTPS)
  Port: 9100/TCP (JetDirect)
  Port: 16992/TCP (Intel vPro HTTP)
  Port: 16993/TCP (Intel vPro HTTPS)
  Port: 62078/TCP (iTunes sync port for iOS device identification)
• Scanned computers to Lansweeper service, if the LsAgent or LsPush scanning agent is used for scanning, with a direct connection to the Lansweeper server
  Port: 9524/TCP or a custom port of your choice
  This port must be open in the firewall of the Lansweeper scanning server, i.e. the server hosting the Lansweeper Server service. You can choose a custom port in the Service Options section of the Configuration > Server Options menu.
