TFTP Server Name
Use the TFTP Server Name screen to identify a TFTP server for configuration file download using DHCP option 66. RFC 2132 defines the option 66 open standard. DHCP option 66 supports the IP address or the host name of a single TFTP server.

Any Port Any Service (APAS) allows a LAN device to use any available port to access any available service from a remote WAN device. Typically, a LAN device, such as a Set Top Box (STB), would have to use a specific port to access video streams from a video server. With APAS, the video streams only need to be received through the specified Bridge WAN interface for the LAN device specified in the APAS rule. You can connect the LAN device to any LAN port. Other LAN devices can access the Internet using the default gateway.
Unlike Port Forwarding, which forwards traffic based on port numbers, you do not need to know the port number for the video traffic from the IPTV server. You just select the LAN device host name or enter its MAC address and select a Bridge WAN interface.
Use the wildcard '*' for a range of MAC addresses for multiple LAN devices. For example, enter 00:13:49:*:*:* for all LAN devices from a vendor with the MAC OUI 00:13:49. (range). Any device with that MAC OUI aa:bb:cc connected to any LAN port on the Zyxel Device can access services or can be accessed for services through the specified Bridge WAN interface. For example, the LAN device could be an STB receiving video streams from a video server, or it could be a server, allowing access to it through the specified Bridge WAN interface.
*You must configure a Bridge WAN interface in advance.
As APAS allows incoming traffic from any port to access any service on a configured LAN device, it may be difficult to distinguish between appropriate and malicious traffic going to the LAN device. Make sure to properly configure firewall rules to protect the LAN device, and monitor network traffic for suspicious activity.
