Awhile back we set up a VPN tunnel between our Cisco ASA devices at our datacenter and our Beijing office. At first, we were able to connect between the Cisco ASA devices over VPN however a few days later we were denied access.
It appears that the government of China does not allow VPN access from anywhere in the United States into mainland China. However they do allow VPN access for users in China to anywhere in the United States. I'm sure this is a common scenario for some of you out there and I'd appreciate the advice.
What are some ways to establish a VPN tunnel between both sites? Perhaps using a cloud based VPN service such as VyprVPN?
