What do I need to do to be able to connect to a Domino server from my local client?

One of my customers setup a new Domino virtual server, but I am unable to reach it with my local Domino client. I added a connection to my contacts database, but still can’t open it while connected to their vpn.

It seems like a security issue on their end, but I don’t know what to tell them to enable me to connect. What do they need to do on their end?

Domino/Notes Version: Rel 12.0.2 on my local, Rel 14.0 on the customers server

First thing is the availability of a connection between the two machines. Secondly the port 1352 must be open. That is the notes port for client connection.
Thirdly any vpn specific issues that impact the connection without reference to notes.

Hi, @bpozsgai.

You may want to consider checking the following:

  1. Check if you can connect to their Network:
    Ping the Server: Even with the VPN connected, try pinging the Domino server’s IP address and then its Fully Qualified Domain Name (FQDN) from your client machine.

  2. Check Port 1352: Domino clients primarily communicate over TCP/IP port 1352 (Notes Remote Procedure Call - NRPC). You can test this from your client using telnet <DominoServerIP> 1352 or Test-NetConnection -ComputerName <DominoServerIP> -Port 1352 (PowerShell). If it connects, the port is open.

  3. Check the Domino port configured in the Server document. The Server Document in their Domino Directory is crucial for controlling client access. They should check the “Security” tab and potentially the “Ports” tab.

  4. Check the firewall on the OS level. Beyond Domino’s internal security, the operating system’s firewall (e.g., Windows Firewall on a Windows server, or iptables/firewalld on Linux) can block connections. They must ensure port 1352 is open on the server’s OS firewall.

Hi bpozsgai,

Hope you are doing well.

As you have mentioned that your Domino server is setup on Virtual machine so in this case you need to check the following Settings.

The virtual server IP address should be connected and reachable from your physical machine.

Additionally, please make sure the Windows firewall is allowed Port 1352 traffic from and to the virtual machine.

Please ping the Virtual Server IP address from the Workstation machine and also perform telnet to Virtual IP address with the NRPC port 1352.

I hope the above information will help in answering your concerns.

Thank you

Thanks & Regards
