NMAP using a CISCO VPN

mog27

For a school project of mine we are supposed to use nmap to locate open ports from the outside and inside of a campus network. Finding ports from the outside is easy enough. However, I am using a CISCO AnyConnect VPN client to connect to the inside of the campus network and run an nmap scan against the internal network but NMAP keeps giving me "nexthost: Failed to determine dst MAC address for target 10.20.0.0"

Any suggestions? Thanks
