i can also confirm that using only the ps3.proxyserver.gui by CF3B5 works.
steps i used were:
1) create a ps3-updatelist.txt and put this in exactly as you see it.
Code:
# US
Dest=84;ImageVersion=00000000;SystemSoftwareVersion=0.00;CDN=http://www.ps3news.com/;CDN_Timeout=30;
save it somewhere you can find it.
2) go to my computer or somewhere with windows explorer browser and paste c:\windows\system32\drivers\etc\hosts in the address bar. a notepad should open up and at the bottom right under 127.0.0.1 localhost
i pasted
Code:
67.15.88.46 fus01.ps3.update.playstation.net
67.15.88.46 fjp01.ps3.update.playstation.net

save and exit.
3) go to the ps3.proxyserver.gui and go to proxy setting tab and for ip address enter the router ip of the computer that you are running the program with.
4) in replace files tab, click add, 1 line with 2 columns appears. on the left side put in "http://fus01.ps3.update.playstation.net/update/ps3/list/us/ps3-updatelist.txt"
and on the right side click the little dot and select the location of the edited ps3-updatelist.txt on your hard drive
5) go back to proxy setting and click the big start button.
6) now go to your ps3 and go to internet connection settings. you do not need to mess with settings UNLESS you connect differently than an automatic router assigned ip. head towards proxy settings and select use.
7) enter in the ip and port of the ps3.proxyserver.gui proxy setting that you entered in step 3.
8) test connection, log in to network.
