Hi,

This could be done through the traffic rules of your device.

This way you can deny all other connections to certain ports or IP addresses and then put one more rule on top that allows one address of your choosing.

Thx for the answer. But is was even esasier, It can be done in portfoward rule in my case.

Anyway is there anyway to set reboot in time when I make changes to configuration? what I want to accomplish: I'm making some changes, but I put wrong config I would like to rollback to working config after for example 3 minutes?

In WebUI, you can only create a backup of all configs, but I believe for you it would be easier if you just copy one config before editing it and, unfortunately, you have to do it manually.
