30AXIS M11 Series - System OptionsUse the following DNS server address - Enter the desired DNS server by specifying the following:• Domain name - Enter the domain(s) to search for the host name used by the network camera. Multiple domains canbe separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, for example,myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where mycompany.com isthe Domain name.• DNS servers – Enter the IP addresses of the primary and secondary DNS servers.Note: This is not mandatory with regard to secondary DNS servers.NTP ConfigurationObtain NTP server address via DHCP - Check this radio button to automatically look up and use the NTP server settings asprovided by DHCP. Click the View button to see the current settings.Use the following NTP server address - To create manual settings, check this radio button and enter the host name or IPaddress of the NTP server.Host Name ConfigurationThe network camera can be accessed using a host name, instead of an IP address. The host name is usually the same as theassigned DNS Name.Link-Local IPv4 AddressThis is enabled by default and assigns the network camera an additional IP address for use with UPnP™. The camera can haveboth a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not affect each other.HTTP and HTTPSThe default HTTP/HTTPS port numbers (80 and 443 respectively) can be changed to any port within the range 1024-65535.This is useful for simple security port mapping, for example.NAT traversal (port mapping) for IPv4A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This is done byforwarding network traffic from the private network to the “outside”, that is, the Internet. Security on the private network(LAN) is increased since most broadband routers are pre-configured to stop attempts to access the private network (LAN) fromthe public network (Internet).Use NAT traversal when your network camera is located on an intranet (LAN) and you wish to make it available from theother (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NATrouter is forwarded to the camera.Notes:• For NAT traversal to work, this must be supported by the broadband router. The router must also support UPnPTM .• The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadbandsharing device” or “Home firewall” but the essential purpose of the device is the same.Enable/Disable – When enabled, the network camera attempts to configure port mapping in a NAT router on your network,using UPnP™. Note that UPnP™ must be enabled in the camera (see System Options > Network > UPnP).Use manually selected NAT router – Select this option to manually select a NAT router and enter the IP address for the routerin the field provided.LAN (intranet) WAN (internet)Broadband(NAT)routerISP
