NAT will automatically translate the private LAN IP address for each system on the LAN to the single public IP address as packets exit the firewall bound for the public Internet. It also performs the reverse translation for returning packets.
<acronym>NAT</acronym> 在當封包要外送到防火牆之外的網際網路時,會自動轉譯每一台電腦在私有 LAN 的 IP 位址成為一個公有 IP 位址,它也同樣會對回傳的封包做反向轉譯。

Security can be tightened further using a "stateful firewall". This type of firewall keeps track of open connections and only allows traffic which either matches an existing connection or opens a new, allowed connection.
使用具狀態防火牆 (<quote>Stateful firewall</quote>) 可以更進一步加強安全性,這種類型的防火牆可持續追蹤連線,只允許與現有連線相符的封包或符合允許條件的新連線通過。

A firewall ruleset can be either "exclusive" or "inclusive". An exclusive firewall allows all traffic through except for the traffic matching the ruleset. An inclusive firewall does the reverse as it only allows traffic matching the rules through and blocks everything else.
防火牆規則集可以為排除式 (<quote>exclusive</quote>) 或者內含式 (<quote>inclusive</quote>),一個排除式的防火牆會允許所有的連線通過除了符合規則集的連線,內含式的防火牆則會反過來只允許符合規則集的連線並封鎖其他任何的連線。

A ruleset contains a group of rules which pass or block packets based on the values contained in the packet. The bi-directional exchange of packets between hosts comprises a session conversation. The firewall ruleset processes both the packets arriving from the public Internet, as well as the packets produced by the system as a response to them. Each TCP/IP service is predefined by its protocol and listening port. Packets destined for a specific service originate from the source address using an unprivileged port and target the specific service port on the destination address. All the above parameters can be used as selection criteria to create rules which will pass or block services.
一個規則集 (Ruleset) 中會有一群根據封包內的資料來判斷通過或封鎖的規則,主機間雙向的封包交換構成一個連線階段的對話,防火牆規則集會同時處理接收自網際網路的封包以及由系統所產生的回應封包,每一個 <acronym>TCP/IP</acronym> 服務都會預先定義其通訊協定以及要傾聽的埠,要送往指定服務的封包會誕生在來源位址,使用一個不需特殊權限的埠並傳送給目標位址上特定服務的埠,所有上述過程中的參數均可用來當做建立規則的篩選條件,來允許或封鎖服務。
