Hello,
The configuration file you are interested in is /etc/config/blocklist.
Depending on what which access type you want to configure, WebUI or SSH, below are a couple of example commands to block set addresses:
- For SSH access:
- uci add blocklist dropbear
- uci set blocklist.@dropbear[-1].ip='<IP_address>'
- uci commit
- For WebUI access:
- uci add uhttpd dropbear
- uci set blocklist.@uhttpd[-1].ip='<IP_address>'
- uci commit
For more details on uci configuration, refer to this page.
It is also advised to update your device's firmware to the latest.
Best regards,
