IP Filter - allow only specific IPs
Posted: 2020-08-22 22:51
Hi,
I'd like to allow access to server only from specific IP addresses, say 1.1.1.1, and 2.2.2.2 and block from all other IP addresses.
So in IP Filter window I enter:
in upper field "not allowed": 0.0.0.0/0
in lower field "allowing":
1.1.1.1
2.2.2.2
I get "Invalid IP address/range/mask" error.
Apparently 0.0.0.0/0 record is not accepted while being accurate CIDR record.
0.0.0.0-255.255.255.255 is not accepted either.
In the combination of 0.0.0.0/1 and 128.0.0.0/1 the first one is not accepted.
What shall I enter in the upper "not allowed" field to effectively block all address space?
Thank you.
