This optional parameter specifies one or more RADIUS packet
types where duplicates are not ignored. NoIgnoreDuplicates is a comma or
space separated list of request types, such as:
- Access-Request
- Accounting-Request
- Status-Server
By default any request with an identical identifier received
from the same NAS within the DupInterval period will be ignored or the
previous reply retransmitted. If the request type is specified in
NoIgnoreDuplicates, it will not be ignored, irrespective of the time since
reception of a previous copy.
# Always handle dups of Accounting-Request packets
