I often have friends to ask me in the Internet. In fact, I am not very clear, but I can distinguish it, and I recommend using BTcomet software under XP, because I use it, I will recommend it. Recently, there are more people, so I have an answer is not very fast, please forgive, there is a problem. How to tell yourself in the intranet or an external network (public network)? Is there a network firewall? Do you support UPnP? Friends with a certain network knowledge have their own judgment, but what should I do with my portal? What is introduced here is a judgment method that does not require any network knowledge: Help BT users understand the network access situation - MSN Messenger "Advance Connection Information" (Note: MSN Messenger, not Windows Messenger .Windows Messenger Advanced Connection Information is different from MSN Messenger.), Which is located in the "Tool" -> "Options" -> "Connection" of the MSN Messenger menu. Advanced connection information has the following types: "Direct Connection" indicates that the user is a public network, and does not use the Internet connection firewall (ICF) that comes with Windows XP. No need to use UPnP. But this situation does not exclude the user installed a third-party network firewall software, such as Norton Network Security Special Police 2002/2003/2004 series, domestic famous Tianwang firewall, etc. When such users are using BT, as long as the port listening to the BT software is not sealed by ISP, it is generally not to set up to achieve the best speed. Users who have installed third-party network firewalls Note that the firewall allows the BT software to listen to the required ports. "Direct connection, using the Internet Connection Firewall (ICF)" means that the user is a public network, using the Internet connection firewall (ICF) that comes with Windows XP, is not necessarily UPnP. Such users want to get BT to get the best download speed, can manually open the corresponding listening ports in the Advanced setting of ICF, or open BitComet "Allow Open Windows Network Sharing and Firewall ICS / ICF Port", under At the time of BitComet, the network connection protection setting is prompted to be determined on the dialog that is about to be changed, allowing BitComet to automatically operate. "Universal Plug and Play (UPNP) Network Address Translation (NAT) indicates that the user is the intranet, the NAT supported by the gateway or router, the gateway or router supports UPnP (and open, currently supporting UPNP gateway" with Windows XP. ICS, Kerio's WinRoute FireWall 5 Series). Such users want to get BT to get the best download speed, preferably BT software that supports UPnP, such as BitComet. "Non-universal Plug and Play (UPNP) Network Address Translation (NAT", "Asymmetric NAT", "Symmetric NAT", "Cascad", etc. Represents the user is the intranet, Internet, gateway or router via gateway or router NAT does not support UPnP, or although support UPnP, UPnP is turned off by ISP and network administrator. Such users are difficult to let BT software get a connection initiated by other downloaders, want to improve the download speed, you can try a BitComet Series with a very strong external connection capability. "Non-UPnP Firewall" is usually appeared along with the NAT type, indicating that the user is an intranet, using a network firewall that does not support UPnP, such as Norton Network Security Special Police 2002, etc. Such users are also difficult to allow BT software to get the connection initiated by other downloaders, want to improve the download speed, or recommend the BitComet Series for the external connection capability.
