Is there a way to block VPN sites that only go by an IP address. There are some VPN clients that makes HTTP or HTTPS connections to VPN servers that only go by IP address. With this, the Firewalla is failing to block these connections. Is there a easy way to write a rule that if there is any HTTPS or HTTP connection that is open for too long and has lot of bandwidth usage, block it? Another approach will be to block any HTTP/HTTPS connection to server that doesn't has a valid DNS record.
