CSF deny issue

[attroll]

I am having trouble with my CSF and denying whole countries.
I am trying to block the country of Chia.
I have the following line in my csf.conf file.
CC_DENY = "CN,RU,VN,NG,RO,UA,IN"
I have restarted my csf after I made changes.

I am still getting IP's from China getting to my server.
I have checked my server logs and there are IP's that start with 175.44, which are from China.

Am I doing something wring in with this or how do I successfully block whole countries?
