AXIS P1357-E Network CameraAbout system optionsNAT 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.• In this context, router refers to any network routing device such as a NAT router, Network router, Internet Gateway,Broadband router, Broadband sharing device, or a software such as a firewall.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 a port in the range 1024–65535. If theport field is empty or contains the default setting, which is 0, a port number is automatically selected when enabling NAT traversal.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.FTPThe FTP server running in the Axis product enables upload of new firmware, user applications, etc. The FTP server can be disabledunder System Options > Network > TCP/IP > Advanced.NoteThis FTP server has nothing to do with the product’s ability to transfer images via FTP to other locations and servers.RTSPThe RTSP server running in the Axis product allows a connecting client to start an H.264 stream. The RTSP port number can bechanged under System Options > Network > TCP/IP > Advanced. The default port is 554.NoteH.264 video streams will not be available if the RTSP server is disabled.SOCKSSOCKS is a networking proxy protocol. The Axis product can be configured to use a SOCKS server to reach networks on the otherside of a firewall or proxy server. This functionality is useful if the Axis product is located on a local network behind a firewall, andnotifications, uploads, alarms, etc need to be sent to a destination outside the local network (for example the Internet).SOCKS is configured under System Options > Network > SOCKS.
