and 20.

tion-requests. The possible values are 1 sec, 2 secs (def), 3 secs, 5 secs and 10

PPP/Max Failure
Write security: 3; Read security: 5
Due to the nature of PPP, configuration options may not be agreed upon be-
tween two PPP peers. This value is the number of configuration-naks that
should occur before an option is configuration-rejected. This allows a connec-
tion to succeed that might otherwise fail. The possible values are 5 (def), 10, 15
and 20.
PPP Profile/Filters
The Express L768/L1.5 can block packets in and out of a WAN port by use of
the filters. They are set up in two steps: 1) define the types of packets that
would be of interest in the Configuration/Security/Filter Defines menu, and
2) set up the filter type and combination of defines that will cause a packet
block.
Filters/WAN-to-LAN (In)
Write security: 2; Read security: 5
The packets which come into the Express L768/L1.5 can be filtered in three
ways:
Disabled (def) - Turns off packet input filtering. No incoming
packets are blocked.
Block All - All incoming packets from the WAN are blocked
except as defined in the Filters/In Exceptions list.
