You need to set up split tunnelling, so that only certain packets are sent across the tunnel, the rest go out in the clear just as normal packets.
In the 3015 create a Network List under Config - Policy Mgmt - Traffic Mgmt - Network List, this list will include your internal networks (traffic you want to be tunnelled). Then go under the Group that the client is connecting to, under the Client Config tab, select Only tunnel networks in the list and select your list in the drop-down box. Reconnect and you're good to go.
Keep in mind split-tunnelling is considered somewhat of a security risk seeing as your PC is now accessable from the Internet AND you have a VPN straight into your internal network. If someone can take over your PC then they have access to everything. You might want to also look into enabling the client firewall stuff as well.
