The INTL Kludge line is used to send messages through non standard network
zones (20 in this example). For fido standard zone 1 you may specify just the
origin net and node as well as destination net and zone and it will default to
zone 1. Also with the direct flag you may either use the _Direct in the status
or add your own FLAGS DIR kludge.
Good luck!
