Link: IP Static ARP
Your Gateway maintains a dynamic Address Resolution Protocol (ARP) table to map IP
addresses to Ethernet (MAC) addresses. It populates this ARP table dynamically, by retriev-
ing IP address/MAC address pairs only when it needs them. Optionally, you can define
static ARP entries to map IP addresses to their corresponding Ethernet MAC addresses.
Unlike dynamic ARP table entries, static ARP table entries do not time out. The IP address
cannot be 0.0.0.0. The Ethernet MAC address entr y is in nn-nn-nn-nn-nn-nn (hexadecimal)
format.
Link: Pinholes
Pinholes allow you to transparently route selected types of network traffic, such as FTP
requests or HTTP (Web) connections, to a specific host behind the Gateway. Creating a pin-
hole allows access traffic originating from a remote connection (WAN) to be sent to the
internal computer (LAN) that is specified in the Pinhole page.
Pinholes are common for applications like multiplayer online games. Refer to software
manufacturer application documentation for specific traffic types and por t numbers.
