There are a number of services we offer that behave differently for 
off-campus users vs. on-campus users (based on IP address) and testing 
both behaviors is difficult while sitting on-campus.

I'm looking for an easy, reliable, and secure way to do this.

At the moment I'm doing a free 7-day trial of Anonymizer Anonymous Surfing 
software ($30/yr), but I want to make sure I'm not missing any good 
alternatives.

Does anyone have any recomnendations or relevant experience?
