You can enable or disable Internet access for a VPG by choosing the appropriate setting for the Use Internet Gateway option when you create a VPG. However, once a VPG has been created, you cannot modify the Use Internet Gateway option.
If you need to change the Use Internet Gateway option, simply create a new VPG with the appropriate settings requied. Please note: creating a new VPG will incur additional setup and service/usage fees. Please refer to: What is the pricing structure for Canal, Direct, Door, and Gate?
