Internet connection impossible when a Wireguard client in connected

2 weeks ago

Model: OC200

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.
