摘要
A system for layer 3 FQDN based split tunnelling includes a VPN gateway and a client device. The VPN gateway receives a DNS response through a physical coding sublayer. The VPN gateway fetches a fully qualified domain name corresponding to the DNS response, and fetches one or more access control list rules from an access control list table for a specific user account. The VPN gateway installs an IP address in the access control list table for each access control list rule and handles requested data traffic to the IP address. The client device creates a virtual tunnel interface route with a port of a transmission control protocol (TCP) listener device and parses the domain name system response. The client device updates a domain name system cache with the fully qualified domain name and the IP address and sends unencrypted network traffic over the virtual tunnel interface route.
