你的浏览器所送出的封包中，也包含供服务器资料回传的本地IP地址。EQL可将这些外传的封包，分散到不同的ISP线路上，但当资料回传时，却只能通过一个IP地址接收，也就是浏览器认为正在使用的那个地址。若是使用ISDN，那么ISP会处理这个问题；一些ISP会为多组线路的拨号接入提供相应的IP地址，但价钱非常昂贵。 <br><br> 在追求速度时，请别忽略了Linux防火墙的效率。在作者办公室有六位用者通过“ IP伪装”防火墙，去存取一部56K模拟调制解调器，工作情况十分良好，只有在有人下载大文件时速度才会变慢。在您决定要加装多条ISP拨号线之前，可以先架设 一部“IP伪装”服务器试试。Windows处理多得IP的方式并非十分有效率，而将 Windows网络与调制解调器隔开，效能的增进将会让你惊讶不已。 <br><br> 简而言之，Linux的用的“IP伪装”法，就是把你的IP藏起来，不让网络上的其他人看到。<br></P>
