Wireguard & LAN Access Issue

Router
1

Hi,

Just installed an AR150 (running v3.216 software) as a Wireguard server. Remote devices connect and can access the internet. However they can not access the LAN. The Wireguard configuration page has a button to "Allow Access Local Network" and it is on.

Any suggestions on how to debug this would be welcome. Thanks in advance.

Hi

This device has been EOL for quite some time, so I no longer have one available for testing on hand.

You may want to trace the route and determine where the issue occurs, then check the firewall-related settings to ensure that the relevant traffic is not being blocked or dropped.

# Windows (Command Prompt)
tracert {your_lan_subnet}

# macOS / Linux
traceroute {your_lan_subnet}

Yes it is an older discontinued unit. However I thought that debugging WireGuard in 2026 would be applicable to debugging WireGuard on a device that went EOL December 31st, 2023.

Thanks

Yes, the usual methods for debugging WireGuard issues are generally the same.

However, without a local device available for testing, we are unable to reproduce the issue on our side, perform the debugging steps ourselves, and identify where the problem may be occurring.

So you may want to check the following:

If you need assistance, you can share the traceroute results and screenshots related to the firewall configuration, and we can help review them.
