AXIS M3026-VE Fixed Dome Network Camera System Options Select Obtain NTP server address via DHCP to use the NTP settings provided by the DHCP server. To make manual settings, select Use the following NTP server address and enter the host name or IP address of the NTP server. Host Name Configuration The Axis product can be accessed using a host name instead of an IP address. The host name is usually the same as the assigned DNS name. The host name is configured under System Options > Network > TCP/IP > Advanced. Select Obtain host name via IPv4 DHCP to use host name provided by the DHCP server running on IPv4. Select 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 Address Link-Local Address is enabled by default and assigns the Axis product an additional IP address which can be used to access the product from other hosts on the same segment on the local network. The product can have a Link-Local IP and a static or DHCP-supplied IP address at the same time. This function can be disabled under System Options > Network > TCP/IP > Advanced. HTTP The HTTP port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition to the default setting, which is 80, any port in the range 1024-65535 can be used. HTTPS The HTTPS port used by the Axis product can be changed under System Options > Network > TCP/IP > Advanced. In addition to the 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 HTTPS on page 41. NAT traversal (port mapping) for IPv4 A network router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwarding network traffic from the private network to the "outside", that is, the Internet. Security on the private network (LAN) is increased since 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) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router is forwarded to the 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", "Broadband sharing 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 in the field. If no router is specified, the product automatically searches for NAT routers on your network. If more than one router is found, the default router is selected. 46
