does not respond to ARP requests or ICMP packets.

37-16 config jwac update_server
Description
This command is used to add or delete a server network address to which the traffic from an
unauthenticated client host will not be blocked by the JWAC Switch. Any servers running ActiveX
need to be able to have access to accomplish authentication. Before the client passes
authentication, it should be added to the Switch with its IP address. For example, the client may
need to access update.microsoft.com or some sites of the Anti-Virus software companies to check
whether the OS or Anti-Virus software of the client are the latest; and so IP addresses of
update.microsoft.com and of Anti-Virus software companies need to be added in the Switch.
Format
config jwac update_server [add | delete] ipaddress <network_address> {[tcp_port
<port_number 1-65535> | udp_port <port_number 1-65535>]}
