General Configuration; Web Administration; Ip White List; Sms Management - CTEK Z45 Series User Manual

General Configuration

 Firewall Status - When enabled the firewall blocks all WAN traffic except for port
80 and the serial pad port if, and only if the serial pad is active. Since an SMS
command (TechNote TN009) can be used to temporarily open ports for ad-hoc
maintenance there are very few reasons to ever disable the firewall.
 XML Interface: Can be enabled to open port 5070 for XML applications
 WAN Ping Response – When Disabled ICMP Ping requests will be ignored
 NAT Traffic to WAN - Must be Enabled for normal operation

Web Administration

Provides a mechanism to enable or disable HTTP access through the WAN, LAN, or both.
Also provides a mechanism to specify an IP port number other than 80 for HTTP access
through the WAN, LAN, or both.

IP White List

to both WAN and LAN side connections.
IP Address (for white list) – specified as an address followed by a netmask in the
Classless Inter-Domain Routing (CIDR) format as in 192.168.1.0/24 to allow the entire
class C range beginning at 192.168.1.0 for LAN administration
Note: If enabled, be sure to create an entry for LAN access.
