A communication control apparatus for executing a data transfer process between an external network and an internal network, includes a first port connected to the internal network, a second port connected to the external network, a storage unit, a determining unit which determines whether or not information to specify an operation environment of the communication control apparatus relating to a data transfer process of network layer level is stored in the storage unit, and an executing unit which executes the data transfer process at the network layer level between the first port and the second port based on the information when the determining unit determinates that the information is stored in the storage unit and executes a data transfer process at data link layer level between the first port and the second port when the determining unit determinates that the information is not stored in the storage unit.
