Hello,

I have strange issue with LAN traffic forwarding on my two Teltonika RUT955 routers.

Software I use is RUT9XX_R_00.06.06. Also tried to use latest RUT9XX_R_00.06.06.1 but that wont fix the issue.

Problem is that devices in LAN will not be reachable periodically. I can resolve that with strange method: changing and saving load balancing configuration. Even rebooting router wont fix that issue and hosts in LAN will not be still reachable after reboot.

More details in first comment.

Simple LAN configuration:

After router reboot situation is same:

Load Balancing configuration before:

Changing Load Balancing configuration and LAN hosts will be accessible:

I even dont use load balancing feature:

Hosts in LAN will be unreachable again after ca 24hours and I can fix that again with changing LB configuration: for example Mobile ratio 3 -> Mobile ratio 2.

Have you tried removing ‘Wired’ from loadbalancing? It looks like it works when you do it, also might be an issue with firewall settings

Hi Meelis,

Please rewrite the latest firmware by NOT choosing 'keep all settings' and try again. If that doesn't solve the issue, Please send me a PM with troubleshoot file so I can check.
