Made a subnet mask change from a 24 to a 16 mask and now the VPN connects, but no one can communicate through to servers or have outlook connect to Exchange. Here is the access-list, vpngroup and ip info:

access-list split permit ip 10.1.1.0 255.255.255.0 9.0.0.0 255.0.0.0 - changed to 10.0.0.0 255.255.0.0

ip address inside 10.1.1.1 255.255.255.0 - changed to 10.0.1.1 255.255.0.0
