This blocks Steam. Is it possible to set up a version that doesn't?

1- Steam cannot be downloaded from valve.
2- Installed Steam cannot open/login

Thank you for your question @Excidiar.

It's hard to formulate a good reply since you provide no context. What rig are you using? What URLs are you using to access these things? More specifically, which domains are being blocked that prevent Steam login?
