FWSM uses port 1521 for SQL*Net. This is the default port used by Oracle for SQL*Net. This
value, however, does not agree with IANA port assignments.
FWSM listens for RADIUS on ports 1645 and 1646. If your RADIUS server uses the standard ports
1812 and 1813, you can configure FWSM to listen to those ports using the authentication-port and
accounting-port commands.
