Block All traffic only allow Google services

Dear Community Member,

Just to ask  a silly question, I have intention for block all network traffic but just do allow all google related services as below:

1) Gmail

2) Google Drive

3) GASMO

4) Google Sheet, Slide, Docs,

I'm using XG135, Firmware SFOS 17.0.6 MR-6

Any possible we can perform it .

Thanks,

Regards,

Peter
