Hi!

We updated our RUT240 to the latest Firmware Version 1.07.1.

After the update only the first IPsec VPN-Connection works. The second one can only establish Phase 1. In Phase 2 we see the tunnel "192.168.22.0/24 === DYNAMIC Tunnel". But this is wrong! It should be "192.168.22.0/24 === 192.168.18.0/24". The first VPN connection (that always works) has the tunnel "192.168.22.0/24 === 192.168.0.0/24".

If we deactivate the first VPN connection (with tunnel 192.168.0.0/24), the second VPN connection is established with tunnel "192.168.22.0/24 === 192.168.18.0/24". After activating the first VPN again, the first one is only connected and the second one is lost again with the dynamic tunnel.

Till the update the both VPN's are working fine.

We already tried deleting and create the second VPN again. We also tried using a different PSK for both VPN's.

Maybe this is a known issue?

Best regards

Nico

Hi,

Perhaps you was keeping old settings when upgrading? If so, try to reinstall router firmware without keeping old settings and reconfigure it manually.

Sure...We used this option, because we need the benefits of this function!

This device isn't in my local office, so I'm not able to configure it, if I reset it.

Best regards

There was made some changes in router firmware which is related with IPsec. So would be better to upgrade without keeping setting.

When will have possibility, upgrade router firmware locally without keeping old settings.

With upgrade to firmware 1.06.x we didn't have this issue and with that version, everything was working fine (on many devices)...

I now made a new firmware-update without keeping our old settings.

But still the same problem. Here I exported the result of "ipsec statusall"

external IP and domains are censored.
