quote from the first page, refine for easier method for some ppl who wanna connect it my way. this feather method works for me. and it should work for u too. 

This method require router which means : telephone line ---> ADSL modem ----> router ---> PC

Stuff you will need.

feather-0.7.5.iso      http://mymirrors.homelinux.org/linux/feather-linux/
vmware server        http://www.vmware.com/download/server/
TcpView for windows http://www.microsoft.com/technet/sysintern...es/TcpView.mspx

1>Once vmware server is installed, open it up and click local host->then ok
2>Then click file.
3>Then click new->virtual machine click next
4>choose typical ->next->linux->version->(drop down menu)other version 2.4xkernel->next
5>Choose a name for it and the place u want to store the virtual machine
6>click next->use bridge networking->next

8>Once that is done click host then virtual network settings->click host virtual network mapping
9>for vMnet0 choose your network adaptor u connect to the net with then leave the rest as they are ->click ok. (choose adapter that connects ur PC to router)
10>In the inventory window in vmware server right click on the virtual machine, click settings then click memory choose 128mb.
11>Then click cd-rom, click use iso image and point that to the feather-0.7.5.iso you downloaded, click ok.

15>Test to make sure your internet connection is working on the vm machine right click on desktop apps->net->firefox. go to yahoo.com or whatever, if u can access the internet in this linuxs' firefox, GOOD.
16>Now to get the ip for your wow server log a character into wow (leave vmware open)
17>alt+tab to desktop and run tcpview.exe scroll down until u find wow and right click and copy the ip address.and paste it into notepad or something.
18>Then close wow.
19>Go back into vmware linux and open console (its on the desktop) and type these


press enter, and type this

enter again

20>now open up a new console window and type ifconfig, now in eth0 look for your inet addr, that is the ip address of the virtual machine (vm.machine.ip). write this address down somewhere.
21>Now go back into windows click start menu click run type cmd then ok.
22>type this
     


23>login to wow. after load screen, alt+tab, go to console in feather, there should be spamming text about transferring data bla bla bla. this means GOOD. now get back to your game and enjoiii!! 

24>if u have trouble to connect like stuck at success, something is wrong with routing above. read carefully. if u dc-ed right after success, try login again. (i sometimes dc-ed once). and if u have no problem connecting but still having high ping, that means ur internet connection is bad. try reconnect with ur usual good ip.

hopefully this helps. credits to those who invented this fix, and those who mentioned it.
