16. Use the Split Tunnel page to specify the split tunneling settings:
• Split Tunnel: Click On to enable the split tunneling feature, or click Off to disable it. Split tunneling allows only traffic that is specified by the VPN client routes to corporate resources through the VPN tunnel. If you enable the split tunneling feature, you need to define the split subnets. To add a subnet, enter the IP address and netmask in the IP Address and Netmask fields and click Add. To delete a subnet, select it from the list and click Delete.
• Split DNS: Split DNS directs DNS packets in clear text through the VPN tunnel for domains served by the corporate DNS. To add a domain, enter domain name that should be resolved by your network's DNS server in the Domain Name field and click Add. To delete a domain, select it from the list and click Delete.
To use Split DNS, you must also enable the split tunneling feature and specify the domains. The Split DNS feature supports up to 10 domains.
