LAN connection over VPN

There was an error rendering this rich post.

Hi, i have a complex network. Computer A is on office LAN with no internet connection, another computer B is connecting remotely to the office network via VPN.

Is there a way to tell teamviewer to connect to computer A via the "Enable Incoming LAN connections" feature, while bypassing Internet?

Firewall exception is already in place, allowing the connection from VPN, to computer A's IP, with port 5938.

From the firewall logs, computer B is able to reach computer A, but right away disconnected quoting "tcp reset from server". From TeamViewer, no error messages nor logs show up.

Hi Ying Q, appreciate your time looking into this for me and my team.

Duly noted that this is beyond the scope of basic support, and i will further speak to your Sales Team to explore this further. =)

Hi @KuokJein,

I believe the error message of "TCP reset from server" is not TeamViewer related. We are unable to assist with the network issue.

Hope you will find out the cause of the connectivity issue soon!

Have a nice day!

Hi @KuokJein,

I am sorry that I missed out your reply post earlier the week.

Meanwhile I have used extra time to check for the scenario and had a discussion with the technical supporter. Let me take this chance to expand the discussion and give you further information.

The message "TCP reset from server" from the firewall log is the record of stating what happened, not an "error" and it indicates the device rejected the request.

About the LAN settings you have described, TeamViewer was not designed to work this way and it is also beyond the scope of the support we may offer. TeamViewer is primarily designed around connections through our router network and the "Via LAN" function is only intended for basic use.

Especially as this is for your employment, I would recommend you to reach out TeamViewer Sales Team☎ for options and see if we can offer support as part of your POC or alternate solutions.

If you have any further question, feel free to let us know.

Best,

Hi Ying_Q, essentially the question is how could i get TeamViewer to connect via the "LAN method" into a sub VPN network?

Was wondering via the "LAN method", does port forwarding / proxy still work?

My organization's policy does not allow the connection to go through internet for security reasons. I am running a POC for my organization before we sign up for the enterprise license, so would really appreciate to get some assistance on this please.
