Note:
When configuring VPN, use the keepalive-track command instead of the keepalive command when the remote peer does not support DPD, or when you want to monitor servers behind the VPN remote peer.
You cannot configure both keepalive-track and ip address dhcp (DHCP Client) on the WAN FastEthernet interface.
