I am also having a similar problem - I've tried to install WoW from an old demo DVD, but when I run the updater to start pulling patches, I am getting "Your computer seems to be behind a firewall". I am getting extremely slow download speeds (700k over the course of an hour). If I try to run the download tool (installWOW.exe) I get "Failed to read information from the internet, please close all applications and try again). I am running Wine 1.1.13, and Ubuntu 8.10, fully updated.
