The following steps to be followed for spit tunnelling
Set the split tunneling policy to only tunnel networks in the list.
Configure network lists and default domain names in the Common Client Parameters section of this screen.
Change the default setting on the client PC's Internet Protocol (TCP/IP) Properties window. Go to Control Panel > Network Connections > VPN > VPN Properties > Networking > Internet Protocol (TCP/IP) > Select Properties > Internet Protocol (TCP/IP) Properties window. Select Advanced and uncheck the box.
Note: If you enable both split tunneling and individual user authentication for a VPN 3002 Hardware Client, you must authenticate only when sending traffic bound for destinations on the other side of the IPSec tunnel.
