When using NC in split tunneling mode checks these items:
1. Under network-Network connect specify the IP pool for remote clients. This ip pool should be unique on your internal network.
2. Route the NC pool on you internal network towards the internal interface of your IVE
3. Create a NC profile to use the NC IP pool
4. Specify for which internal networks NC will perform VPN ( this is split tunneling ; otherwise all traffic will be routed through VPN)
5. Create an access-list for this role under resource-pol-NC to allow traffic.
Goodluck,
