回复：谢谢，请问还有两条打入线路的选择吗？DDNS fwd 听着有一点悬。

PAP2 or PAP2T has two lines in, I prefer spa2102, which has 2 FXS phone ports, and has 1 wan line and 1 lan line. it allow you to connect your cable modem to the wan port, and connect your PC to the lan port. so that you do not need to buy a router for connection to your cable modem to your PC. usually cable modem/or DSL modem only give you 1 lan to connect to your work.
