#    If siproxd is not running on the host doing the masquerading

#    the masquerading router: define if_inbound and if_outbound to
#    point to the same interface (the inbound interface). In *addition*

#    Multiple entries may be separated by commas NO SPACES ARE ALLOWED!!
#    Empty list means 'does not apply' - no filtering is done then.
#    For *allow* lists this means: always allow, for *deny* lists that
#    this means never deny.

#    hosts_allow_reg: defines nets from which we accept registrations
