Axis Communications 211M NTP Configuration, Host Name Configuration, Link-Local IPv4 Address

AXIS 211M - System Options

Use 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 AXIS 211M. Multiple domains can be separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, e.g. myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where mycompany.com is the Domain name.

DNS servers - enter the IP addresses of the primary and secondary DNS servers.

NTP Configuration

Obtain NTP server address via DHCP - check this radio button to automatically look up and use the NTP server settings as provided by DHCP. Click the View button to see the current settings.

Use the following NTP server address - to make manual settings, check this radio button and enter the host name or IP address of the NTP server.

Note: If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Network > TCP/IP below.

Host Name Configuration

The AXIS 211M can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned DNS Name. For more information, see the online help.

Link-Local IPv4 Address

This is enabled by default and assigns the AXIS 211M an additional IP address for use with UPnP™. The AXIS 211M can have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not affect each other.

HTTP

The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is useful for, e.g. simple security port mapping.

HTTPS

If applicable, enter the HTTPS port the AXIS 211M will use. The default setting (443) can be changed to any port within the range 1024-65535. HTTPS is used to provide encrypted web browsing.

NAT traversal (port mapping)

A broadband 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” i.e. the Internet. Security on the private network (LAN) is increased since most broadband routers are pre-configured to stop any attempts to access the private network (LAN) from the public network/Internet.

Use NAT traversal when your AXIS 211M 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 will be forwarded to the camera.
