This one is a tad tricky, becuase RADIUS uses UDP and RADIUS authenticates
the request. You need to add an entry in your Emerald for your firewall.
The secret will be what you set in modusmail. Have modusmail send the
RADIUS request to your firewall.
Finally, define a rule in your firewall allowing port 1812 incoming from
modusmail to port 1812 (or whatever you have RadiusNT listening on) on
your RADIUS server. It will be a UDP rule and you'll also need to allow
a secondary connection UDP from the RadiusNT back (the reply). This is
the tricky part and you'll need to consult your firewall documentation on
secondary UDP connections.
