I have tried to add a new rule to the firewall, to exclude a device identified with its MAC address from the network based on my RUT955 unit.
From Network → Firewall → Traffic rules I selected “lan” for both the Source zone and destination zone. Maybe I did wrong there, as soon after I applied the change, I’ve lost the remote RUT955: no longer visible via RMS, all the connected hardware looks offline.
Is there any possibility to fix this via sms, as the RUT955 is remote? If not, what is the best approach to avoid resetting the unit to factory settings?
To quickly restore your remote RUT955 connection without losing any settings or doing a factory reset, you can temporarily disable the router’s firewall remotely via SMS. Once the router is back online in RMS, you can clean up the rule.
Here is the step-by-step solution:
Recover Your Remote RUT955 via SMS
Since you have lost the RMS connection, you can send three simple SMS commands to the router’s SIM card number to disable the blocking rule and reboot the device.
Note: Replace <Router_Password> with your actual router admin password (for example: Admin123).
Find the firewall rules (Send this SMS): <Router_Password> uci show firewall
(Look through the reply to find the rule number you recently created, such as firewall.cfg13abc or a rule ending in .name=‘test’).
Disable the rule (Send this SMS - replace “19” with your rule’s identifier if it is different): <Router_Password> uci set firewall.19.enabled=0
Reboot the router to apply changes (Send this SMS): <Router_Password> reboot
Within a few minutes of sending these commands, the router will reboot with the blocking rule disabled, and your RUT955 will instantly appear Online in your RMS dashboard.
Once you are back in, go to Network → Firewall → Traffic rules, delete or fix the problematic rule, and then everything will be back to working perfectly.
The solution suggested by @zJakie is likely the best course of action, provided that the device has a SIM card installed and you know the SIM card’s phone number. For more information about UCI commands, please refer to the following Wiki article:
If the device configuration was previously saved as a profile before the firewall changes were made, you can restore the previous configuration using the SMS Utilities feature. The Change profile SMS rule allows you to switch the device’s configuration to a specific saved profile.
The SMS command format is:
<password> pr <profile_name>
Please note that this method will only work if the configuration was previously saved under System → Administration → Profiles. If no profile was created before the firewall changes, the SMS rule cannot be used to restore the configuration.
