VPN Router

I need a simple and very "flat design" pictogram showing the following: We sell a router (internet box) that opens a secure VPN. It goes between the customer's Satellite TV box (pay-tv set top box) and their existing wifi internet router. Two pictograms: 1 The pictogram is showing the set-topbox with TV (all simplified) connected to our router and our router establishing a VPN through the existing router. TV/set-top > our VPN router > existing router All connected through ethernet cable and logos showing the connection types throughout. 2. SAME as above, BUT the there is ONE additional tool: a little wifi box. So the set up is: TV/set-top > (cabled) Wifi Box >>> wifi connection to our VPN router > wired connection to existing router (ethernet) I need this to be very simple, smart designed so people understand. It needs to be a flat black and white design - except for our VPN router which may stick out using another color. Even a non-tech-savvy person (like your mom or my little brother) must be able to "get it" by looking at the set up. Send reference to existing work when applying please!
