To achieve the goal of excluding some servers from the VPN tunnel and accessing them directly, the engineer must modify the group policy that is applied to the remote access VPN users. The group policy contains the settings for split tunneling, which is a feature that allows the VPN client to route some traffic through the VPN tunnel and some traffic directly to the internet. Split tunneling can be configured based on the destination IP address, the application, or the domain name of the traffic. By modifying the group policy, the engineer can specify which servers or networks should be excluded from the VPN tunnel and accessed directly by the VPN client. This can improve the performance and efficiency of the VPN connection, as well as reduce the load on the VPN gateway and the corporate network. However, split tunneling also introduces some security risks, such as exposing the VPN client to internet threats, bypassing the corporate firewall and security policies, and leaking sensitive data. Therefore, the engineer must carefully evaluate the trade-offs and best practices of using split tunneling for remote access VPNs. References :=
