WindowsXP Firewall
23.07.2003 11:18

The Windows XP firewall is generally not recommended as it isa very basic form of firewall. If you want to use it anyway these steps are necessary:

1. Open eMule
2. Click Preferences > Connection
3. Write down the client port value (default 4662)
4. Also note the UDP port value (default 4672)
5. Close eMule and your internet connection
6. In On Windows XP click Start, and then click My Network Places.
7. Go to Network Tasks, click View Network Connections. (Alternatively, you can right-click My Network Places and click Properties.)
8. Right-click the connection you use for the Internet and choose Properties
9. Click the Advanced tab, and then click Settings.
If the Settings button is unavailable, ICF is not enabled on this connection and you do not need to open any ports (they are all already open).
10. Click Add to open a new port.
11. Type a name in the Description box, for example, "eMule : TCP Incoming".
12. Type 127.0.0.1 in the Name or IP address of the computer hosting this service on your network box. You can specify the IP address of an internal computer; however, in most cases, you use 127.0.0.1
13. Type the client port you wrote down in step #3 in the External port and Internal port boxes.
14. Choose TCP, and then click OK.
15. Click Add to open a new port again.
16. This time choose a name like "eMule : UDP Incoming"
17. see #12
18. Now External port and Internal port is the value you noted in step #4.
19. Choose UDP, and click OK.
If you change your client port later, you need to reconfigure the rule above on your firewall.
