AXIS Q1931–E PT Mount Thermal Network CameraSystem OptionsSelect Use the host name to set the host name manually.Select Enable dynamic DNS updates to dynamically update local DNS servers whenever the Axis product’s IP address changes.For more information, see the online help .Link-Local IPv4 AddressLink-Local Address is enabled by default and assigns the Axis product an additional IP address which can be used to accessthe product from other hosts on the same segment on the local network. The product can have a Link-Local IP and a staticor DHCP-supplied IP address at the same time.This function can be disabled under System Options > Network > TCP/IP > Advanced.HTTPThe HTTP port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition to thedefault setting, which is 80, any port in the range 1024–65535 can be used.HTTPSThe HTTPS port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition tothe default setting, which is 443, any port in the range 1024–65535 can be used.To enable HTTPS, go to System Options > Security > HTTPS. For more information, see .NAT traversal (port mapping) for IPv4A network router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwardingnetwork traffic from the private network to the “outside”, that is, the Internet. Security on the private network (LAN) is increasedsince most routers are pre-configured to stop attempts to access the private network (LAN) from the public network (Internet).Use NAT traversal when the Axis product is located on an intranet (LAN) and you wish to make it available from the other (WAN) sideof a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router is forwarded tothe product.NAT traversal is configured under System Options > Network > TCP/IP > Advanced.Note• For NAT traversal to work, this must be supported by the router. The router must also support UPnPTM.• The router has many different names: “NAT router”, “Network router”, “Internet Gateway”, ”Broadband router”, “Broadbandsharing device” or “Home firewall” but the essential purpose of the device is the same.Enable/Disable - When enabled, the Axis product attempts to configure port mapping in a NAT router on your network, using UPnPTM.Note that UPnPTM must be enabled in the product (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 router inthe field. If no router is specified, the product automatically searches for NAT routers on your network. If more than one router isfound, the default router is selected.Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in the field. If no port isentered here, a port number is automatically selected when NAT traversal is enabled.Note• An alternative HTTP port can be used or be active even if NAT traversal is disabled. This is useful if your NAT router does notsupport UPnP and you need to manually configure port forwarding in the NAT router.• If you attempt to manually enter a port that is already in use, another available port is automatically selected.• When the port is selected automatically it is displayed in this field. To change this, enter a new port number and click Save.42
