  Depending on what functions you use, there are several firewall settings that will need to be checked. This is the responsibility of your IT professional, and not Execu/Tech Systems 
These are the default settings required by our software. 

All Applications
  • (Users should be able to access this help site)
  • TCP/IP Ports 80 and 443 to www.execu-tech.com or (Execu/Tech website, help site, hosted tools)
  • TCP and UDP ports 135 - 139 and 445. (This is the default SMB ports and typically not blocked between client and server unless a firewall sits between them. This allows network shares.)

  Cloud Hosting
  • Outgoing port 3389 to an IP address that will be provided once your cloud system is configured. 

  • Shift4 Credit Card Processing from the client to the server where Shift4's UTG is installed - Contact Shift4 to Verify (702) 597-2480

    • TCP/IP Port 443 to *.i4go.com (required for i4Go V2)
      Shift4 maintains many IP addresses to ensure redundancy. You must contact Shift4 for a current list of IP addresses. 

  • The following are used to obtain the client's current public IP address. There are several servers used in case one or more do not respond in a timely manner. No data is sent to these addresses. A request is made to the URL and it responds with the IP address in plain text.
    Clink the links and if they open a browser and show your IP address, then your firewall settings are good.
