Hello,
Remote access to the router is disabled by default.
To solve your issue, you could simply create a new traffic rule excluding your desired IPs, by logging to the WebUI and navigating to Network -> Firewall -> Traffic Rules.
Next scroll to the bottom of the page to the Add new instance section. Select type Add new forward rule, enter name, leave source zone as wan and destination zone as lan, press Add.
In the rule configuration window enter source IPs, from which you will be connecting to the device remotely. Change destination zone to Device (input), enter destination port 443 or 80 or both, depending on your needs.
Save and apply.
Best regards,
Žygimantas
