1. An in-vehicle communication apparatus connected to a first communication network and a second communication network for relaying a signal to be transmitted and received between the first communication network and the second communication network, the in-vehicle communication apparatus comprising:
at least one processor;
a relay unit configured to, using the at least one processor,
receive a first signal from the first communication network;
relay the first signal received from the first communication network to the second communication network as a second signal; and
add an ID to the second signal to indicate that the second signal is to be sent to the second communication network by the relay unit; and
an illegality determination unit configured to, using the at least one processor,
perform a first processing of determining whether the first signal received from the first communication network by the relay unit is an illegal signal; and
set a second processing of determining whether the second signal to be sent by the relay unit to the second communication network is an illegal signal to be lighter than the first processing.
