Domain name - enter the domain(s) to search for the host name used by the AXIS 223M. 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 223M 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, please see the online help.
Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 223M an additional IP address for use with UPnP
223M 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 223M 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 223M 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.
Notes:
•
For NAT traversal to work, this must also be supported by the broadband router.
•
The broadband router has many different names: "NAT router", "Network router", Internet Gateway", "Broadband
sharing device" or "Home firewall" but the essential purpose of the device is the same.
