I was tasked in deploying Google Apps for business and I have multiple offices in China which has to be on it. 

Anyone knows how can I bypass china's deep packet inspection? 

Given my company's health Mpls is very expensive now. 

Constantly connecting to vpn poses issues such as having all 500 users in China to log in every time they need to check emails as well as the huge traffic volume at the vpn gateway. 

Does proxy server work? Any work around for enterprise solution?
