ER605 v2.0 reboots on wireguard VPN connect
I'm using wireguard server on the ER605 and connecting multiple clients - windows laptops.
If it matters, on the same WAN interface I have a IPsec VPN configured as well.
I upgraded to latest firmware version available for V2.0 today - ER605(UN)_V2_2.2.6 Build 20240718 because randomly some VPNs would stop receiving traffic completly from the VPN. Using wireshark I see only keepalives coming in, and a whole lot going out, but no responses.
My wireguard clients are configured to tunnel all traffic.
On upgrade to firmware 2.2.6 the ER605 completely reboots when a wireguard client connects with the previously created wireguard server.
I suspected some kind of bug so I deleted the old wireguard server and created a new one.
How did it fail again:
- I added the first client, connected, all looked good, disconnected the client.
- Added the second client, connected, all looked good, disconnected the client.
- Added the third client, connected, router crashed.
I'm not sure if its a core-dump or something else, but its obviously not good.
I'm downgrading to 2.2.5 now to see if the issue exists in there too, however I doubt it, because from the release notes there's been wireguard fixes in 2.2.6 only.
Edit: happens with 2.2.5 too
