linerate not configured for free tier, should I be able to experiment with it?

I'm not looking for setting up proxies particularly. We have a system setup inside a firewall and no traffic is supposed to go to the internet under any circumstance. I can setup the http/s proxy in bash of the f5 Linerate, and ping the activate.f5.com and callhome addresses just fine, but the proxy setting is not in effect when trying to activate via web UI or CLI.
