Cisco VPN Client users might receive this error when they attempt the connection with the head end VPN device.

"Attempted to assign network or broadcast IP address, removing (x.x.x.x) from pool" or "VPN client drops connection frequently on first attempt" or "Security VPN Connection terminated by tier. Reason 433."

Solution

The problem might be with the IP pool assignment either through ASA/PIX or Radius server. Use the debug crypto command in order to verify that the netmask and IP addresses are correct. Also, verify that the pool does not include the network address and the broadcast address. Radius servers must be able to assign the proper IP addresses to the clients.
