網(wǎng)關(guān)（Gateway）又稱網(wǎng)間連接器、協(xié)議轉(zhuǎn)換器。網(wǎng)關(guān)在傳輸層上以實現(xiàn)網(wǎng)絡(luò)互連，是復(fù)雜的網(wǎng)絡(luò)互連設(shè)備，僅用于兩個高層協(xié)議不同的網(wǎng)絡(luò)互連。網(wǎng)關(guān)的結(jié)構(gòu)也和路由器類似，不同的是互連層。網(wǎng)關(guān)既可以用于廣域網(wǎng)互連，也可以用于局域網(wǎng)互連。可以說，網(wǎng)關(guān)是一種充當(dāng)轉(zhuǎn)換重任的計算機(jī)系統(tǒng)或設(shè)備。在使用不同的通信協(xié)議、數(shù)據(jù)格式或語言，甚至體系結(jié)構(gòu)完全不同的兩種系統(tǒng)之間，網(wǎng)關(guān)是一個翻譯器。與網(wǎng)橋只是簡單地傳達(dá)信息不同，網(wǎng)關(guān)對收到的信息要重新打包，以適應(yīng)目的系統(tǒng)的需求。同時，網(wǎng)關(guān)也可以提供過濾和安全功能。大多數(shù)網(wǎng)關(guān)運(yùn)行在OSI 7層協(xié)議的頂層——應(yīng)用層。
