Filters
The TA 544 can block packets in and out of a WAN port by use of the filters. They are set up on a per-
Connection List profile basis. They are set up in two steps: (1) define the types of packets that would be
of interest, and (2) set up the filter type and combination of defines that will cause a packet block.

may not be agreed upon between two PPP peers.
This value is the number of configuration-naks
that should occur before an option is configura-
tion-rejected. This allows a connection to suc-
ceed that might otherwise fail. The possible
values are 5 (def), 10, 15 and 20.
