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 entry 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 port numbers.

Conﬁgure Speciﬁc Pinholes. Planning for Your Pinholes. Determine if any

of the service applications that you want to provide on your LAN stations use TCP or UDP

protocols. If an application does, then you must conﬁgure a pinhole to implement port for-

warding. This is accessed from the Advanced -> Pinholes page.
