Hardware Version: V1
Firmware Version: 1.31.3 Build 20240620 Rel.80383

Hello,

I configured a Wireguard Service .

I tested with one peer connection from my 5g phone in the phone side it works fine and i can access to servers in my network.

 

The issue is in the internal network .

All devices connected in the network are cut from internet when the wireguard client is connected. When i disconnect it it comes back after 20 seconds.

 

Can you highligh me about a way to investigate?

Thanks in advanced

Franck

Hi  @Taxesurleprix74 

 

When the VPN client connects, it could potentially cause an IP conflict within the local area network (LAN). Check if the VPN client is configured to use an IP address range that overlaps with the LAN's IP range.

Hi  @Taxesurleprix74 

 

Sorry for the late reply.

 

 

Is the issue happening on all kinds of VPN clients?

 

Has the issue been fixed? If not, please let us know.

 

Side note: please mention me in the subsequent reply so I can get your message in time.

Hi Vincent,

I guess I have a similar problem as the founding post.


I created WireGuard VPN via OMADA OC200, and then I made one profile. Everything works correctly, BUT when I made a second profile (user) for a mobile phone, and when I connect, my main router ER605 crashes. The device simply restarts :-(.


But when I deactivate the second user in the list, the main ER605 router works fine.


I can send screenshots of the settings. Maybe you can think of something.

 

My firmware is probably up-to-date everywhere.

 

Thank you very much.

Thank you very much. I just found it now. I downloaded the FW. I will update during the day tomorrow.

 

Add: I did the update and everything works perfectly( https://community.tp-link.com/en/business/forum/topic/714842 ). Thank you everyone.
