Model: ER8411  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20230705 Rel.64091

Hi,

 

yesterday I replaced my ER7206 by a ER8411 and realized that the OpenVPN Client-to-Site is no longer working although it is statet as introduced with firmware 1.1.0

 

The Insight shows, that it is connected, but I cannot connect to IP via VPN connection.

 

The Router is used in Controller Mode with Linux Controller 5.12.7.

 

I would be happy if someone could help me.

 

Regards,

Matthias

there is somthing with UDP on this router, try and configure OpenVPN server with TCP. for me this work, very slow and far away from the spec on this device.

 

OpenVPN is also very oudated, work only whit OpenVPN 2.4 or older. so connection to more modern system will not work from any TP-Link device.

This is not true. My previous ER7206 was very well doing with OpenVPN core 3.

I read already the TCP stuff, which is not a solution for me, as the OpenVPN server is configured to not accept connection via TCP.

I had to install a new OpenVPN server with TCP to get it to work, so I think this is the only option on ER8411. and the server was installed in 2.4 or older compatibility to get it to work.. all the other routers like ER605v2 ER707-M2 work with UDP but not ER8411

  @MR.S 

Thanks for Feedback. Nevertheless, this would be a bad workaround. Not a solution.

I know that this topic is discussed in several threads here.

Hi @MatthiasL22 

Thanks for posting in our business forum.

So I am not gonna focus on what MR.S said until we try to fix the issue you have with the router.

In the original post, you said that you cannot access the IP, any luck that you can ping it?

In the Insight, you see the tunnel is up and running but the IP is not working. Can you verify that your setup is correct? Would love to see some pictures and verifications.

 

If you are facing the exact problem as MR.S, I can escalate your case for further analysis and require your cooperation. So for now, I'll focus on your issue.

  @Clive_A 

Thanks for reply and I would appreciate escalation on that. 
Pictures of what do you need exactly?

 

Even a ping is not possible. 
I do not think that anything is configured wrong because with the same settings and er7206 everything was working.

Nothing else has been configured on the router and the tunnel shows up. Is this correct about your setup? Just one VPN entry?

ER8411 is hosting the server? What IP address did you ping? The gateway IP?

 

The escalation requires a basic understanding of your issue and setup.

I made some pictures. 
ER8411 is VPN client. 
hope it helps. 
I tried to ping not only the gateway IP but also other IPs which are known to be available via VPN

So you've tried the command prompt on the PC which is in VLAN 30 as well?

What if you use this exact profile on the phone with the OpenVPN app, does it connect well and work with the ping?
