i did the above steps but still i can access to this ip address actually its captive portal ip address and i want that only i can access this ip not others.
You want the 10.0.0.1 ip set as destination, and your device ip as source ip you can use the ! symbol which stands for everything except for ip after symbol, or as source mac if you click on advanced settings.
If 10.0.0.1 is the lan subnet and not a other router.
10.0.0.1 is a captive portal ip address if i want to log in to captive portal i have to go this address but i dont want others can visit to the captive portal.
due to lack of my openwrt knowlege,
destination is - 10.0.0.1
source is my device. ?
I mean you can enable IP access to your router and block it for connected devices. In this case:
Source zone: LAN
Destination: WAN (if ip device is on WAN)
Rest is correct
