The A

A

check box enables the NetVanta 2000 series HTTP configuration access from the
Internet (WAN) interface. By default, HTTP configuration access is disabled on the Internet (WAN)
interface.
The

ING
check box controls the NetVanta 2000 series's response to ICMP Echo Request messages
received on the Internet (WAN) interface. Selecting this checkbox configures the NetVanta 2000 series to
reply to the ICMP Echo Request received on the WAN interface. By default, Ping response is disabled on
the Internet (WAN) interface.
Disabling ping on the Internet (WAN) network interface filters out ICMP-based trace route traffic and
gives implicit protection to the ADVANTA 2100 and the corporate network behind it from many ICMP
Echo message based cyber attacks (Ping of Death, Ping Flood, Smurf, etc.).
The
A
LLOW
T
ELNET
check box enables telnet access to the NetVanta 2000 series system on the Internet
(WAN) interface. By default, telnet access to the ADVANTA 2100 is disabled on the Internet (WAN)
interface.
