It isn't a good idea to circumvent corporate environment networks. they're there for a reason, and doing it shows a lack of professionalism and dis-respect for the organization process, procedures, and security. Yes it takes weeks/months to get access, then it takes weeks/months to get access. You don't want to be held liable for opening a backdoor to confidential information, or compromising their security.

I was on a project once where a consultant had dropped their laptop and it had taken a week or two to get fixed. After that everyone had to use a laptop provided by the client. When we scaled up the project with 3 more developers the project manager who had set up this policy discovered that the lead time for 3 dev laptops meant that the new developers got to be bored for a month at a fairly high hourly rate.
