I hoping that this was a typo.  I pulled out all the registered RADIUS 
ports from http://www.iana.org/assignments/port-numbers and 1645/1646:

sightline       1645/tcp  SightLine
sightline       1645/udp  SightLine
#                         admin <iana&sightlinesystems.com>
sa-msg-port     1646/tcp  sa-msg-port
sa-msg-port     1646/udp  sa-msg-port
#                         Eric Whitehill <Eric.Whitehill&itt.com>


radius          1812/tcp    RADIUS
radius          1812/udp    RADIUS
#                           [RFC2865]
radius-acct     1813/tcp    RADIUS Accounting
radius-acct     1813/udp    RADIUS Accounting
#                           [RFC2866]
radsec          2083/tcp   Secure Radius Service
radsec          2083/udp   Secure Radius Service
#                          Mike McCauley <mikem&open.com.au> May 2005
radius-dynauth  3799/tcp   RADIUS Dynamic Authorization
radius-dynauth  3799/udp   RADIUS Dynamic Authorization
#                          RFC 3576 - July 2003

Should 1812 & 1813 be listed or also 2083 & 3799?
