Which ports of my firewall need to be opened?

After installing the Teampel Server program, if the server operating system has a firewall or a firewall installed, or if the computer facilities where the server located have a hardware firewall, then you have to open the relevant network ports required by Teampel on the firewall. In this way, Teampel Clients on other computers can connect to Teampel Server and function normally.

  1. TCP & UDP 35000, HTTPS 443 (optional): GaaihoConnectSvr.exe (services Links)
  2. TCP & UDP 35001: GaaihoFileSvr.exe (data transfer)
  3. TCP & UDP 35002, 35003: GaaihoManageSvr.exe (account management system)
  4. TCP & UDP 35004, RTP port range UDP 35100~40000:GaaihoSIPSvr.exe (embedded SIP service)
    (How to enable embedded SIP VoIP service under port forwarding environment?)

 

Recommendation:

  • Above 1. & 2. must be emabled (HTTPS 443 is optional) in order for Teampel to perform properly.
  • Enable 3. if you need to access "account management system" via the internet.
  • Enable 4. if using Teampel voice call feature. 

 

Note:

If the client connects to Teampel server through a proxy server, make sure the 443 port is opened and not occupied.

The port numbers preset by the server can be set up through the profile of the corresponding services.

 

How to check my connectivity with Teampel Server?

  1. Check the connection between the client and the server through pinging IP.
    >Ping 192.168.7.131

     
  2. Check if a certain port of the server is accessible through Telnet IP port. For example:
    >Telnet 192.168.7.131 35000
    If the port is available, it will enter an interface; if the port is not available, the following picture will show:

    In this case, there may be a problem with the Teampel Server firewall settings. Please refer to "How can I manually set up the Windows operating system firewall?"

 

While executing Telnet command, if prompted "Telnet is not recognized as an internal or external command", please refer to the following instructions:

On Windows7/Windows8 /Windows10:

  1. Click "Start" > "Control Panel" > "Programs";
  2. In the left panel, click "Turn Windows features on or off" window;
  3. Click "Telnet Client";
  4. Click "OK" and wait a few minutes to complete the installation.

 

On Windows Server 2008 R2:

  1. Click "Start" > "Control Panel" > "Programs";
  2. In the left panel, click "Turn Windows features on or off" window to open "Server management interface";
