Nautica Configuration Wizard Reference Guide
Parameter: Proxy Arp
Default: Disabled
Options: Enabled or Disabled
Function: Enables or disables Proxy ARP
Instructions: Enabling Proxy Arp allows the Nautica 200 to respond
to any ARP requests that are known to be associated to
this route.
An ARP Request is a request for a MAC address to
associate with a known IP address. With Proxy ARP
enabled, all these requests will be sent out along the path
specified in the Path parameter (
page 12-5 ). In effect the
Nautica 200 pretends to be the host specified in the
requested ARP. It is a feature used more commonly with
single host addressing (Chapter 2) and Cul-de-sac
routing (Chapter 4).
Parameter: Cul-de-sac Route
Default: Disabled
Options: Disabled, Enabled
Function: Marks this route as a Cul-de-sac route
Instructions: Cul-de-sac routes are routes linking into a remote
network that uses the same subnet as the local LAN. If
you set up a Cul-de-sac route, you must also select the
Proxy Arp parameter.
TCP/IP Filters
Filtering allows you to specifically allow or disallow calls into the
Nautica 200. If a filter is created, it will work according to the IP
Filtering option set up in
Advanced >System
( page 7-9 ).
