No, please see the readme file of the module. It adds a maxfwd header
with the value given as parameter, if there is no maxfwd header. If the
header already exists, it compares the value decremented with one against 0.

Be sure you do not do local loops. Otherwise, besides doing extra
processing (remove+add header) to change the value of maxfwd to 1,
there should not be any harm.
