EW50 Industrial LTE Cellular Gateway

5.2.4 Options
There are some additional useful firewall options in this page.
“Stealth Mode” lets the gateway not respond to port scans from the WAN so that makes it less susceptible to
discovery and attacks on the Internet. ”SPI” enables gateway to record the packet information like IP address,
port address, ACK, SEQ number and so on while they pass through the gateway, and the gateway checks every
incoming packet to detect if the packet is valid.
“Discard Ping from WAN” makes any host on the WAN side unable to ping this gateway. And finally, “Remote
Administrator Hosts” enables you to perform administration tasks from a remote host. If this feature is
enabled, only specified IP address(es) can perform remote administration.
