Hi,
You need to configure split tunneling. This link should help: http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/configuration/guide/asa_84_cli_config/vpn_groups.html#wp1053494
An example configuration on the Cisco ASA is as follows:
access-list NETWORKS-TO-PERMIT standard permit 192.168.10.0 255.255.255.0
!
group-policy VPN-GRP-POLICY attributes
split-tunnel-policy tunnelspecified
split-tunnel-network-list value NETWORKS-TO-PERMIT
!
tunnel-group VPN-TUNNEL-GRP general-attributes
default-group-policy VPN-GRP-POLICY
You can also specify networks to exclude using split-tunnel-policy excludespecified
