Port no block

Post by hackerscomputer »

hello
im try to open / block port by country with this settings

all country:
TCP_IN = 20,25,53,80,443,465,587,993,995,1167,49152:65534,2080,2443,49152:65534

only from IT
CC_ALLOW_PORTS = IT
CC_ALLOW_PORTS_TCP = 21,110,143,2077,2078,2082,2083,2086,2087,2095,2096

deny all CHINA
CC_DENY = CN

deny BR,VN,TH
CC_DENY_PORTS = BR,VN,TH
CC_DENY_PORTS_TCP = 993,995,465,587

seem all works great but today i want to try to remove port 143 to prevent user to access imap on that port and change like CC_ALLOW_PORTS_TCP:
CC_ALLOW_PORTS_TCP = 21,110,2077,2078,2082,2083,2086,2087,2095,2096

but i found that port 143 is always open and i can connect to it but only from IT (test from different IT location) while with online port check tools, not from IT result closed, how can be possible?

thanks
