set ip wan addr-mapping { off | on }
Specifies whether network address translation (NAT) is enabled for
the WAN port on the Cayman 2E-H.
set ip wan proxy-arp { on | off }
Specifies whether you want the Cayman 2E-H to respond when the
it receives an address resolution protocol for devices behind it. By
default, proxy ARP is turned off.
NAT default settings let you specify whether you want your Cayman
2E-H to forward NAT traffic to a default server when it doesn't know
what else to do with it. The NAT default host function is useful in
situations where you cannot create a specific NAT pinhole for a
traffic stream because you cannot anticipate what port number an
application might use. For example, some network games select
arbitrary port numbers when a connection is being opened. By
identifying your computer (or another host on your network) as a
NAT default server, you can specify that NAT traffic that would
otherwise be discarded by the Cayman 2E-H should be directed to a
specific hosts.
set nat-default option { off | on }
Specifies whether you want your Cayman 2E-H to forward NAT
traffic to a default server when it doesn't know what else to do with
it.
set nat-default address ip-address
Specifies the IP address of the default NAT server.
NAT pinholes let you pass specific types of network traffic through
the NAT interfaces on the Cayman 2E-H. NAT pinholes allow you to
route selected types of network traffic, such as FTP requests or HTTP
(Web) connections, to a specific host behind the Cayman 2E-H
transparently.
