I'm currently evaluating several firewalls. My goal is to block all traffics from VPN providers. We have the VPN IP address list from the IP2Proxy in the following format with IP address ranges in decimal format.

"17496733","17496733","VPN","TH","Thailand"
"17496784","17496784","VPN","TH","Thailand"
"17543533","17543533","VPN","KR","Korea (Republic of)"
"17544563","17544563","VPN","KR","Korea (Republic of)"

How can we use NG Firewall to block the 11 millions VPN servers?
