This may be a weird question but if someone hops/connects to my wifi from their phone is there a way to block, lets say the facebook app, from connecting to that users facebook account? In other words, block them form accessing their facebook account using my wifi.
The content filter on my network firewall (Zywall USG20) only works with port 80 (http not https).
How does the app connect to the users account? It must use DNS to resolve the name "facebook". I can create an "A" record in DNS to resolve facebook to 0.0.0.0 in which it will work for a PC but I'm guessing if the cellular carrier has their own DNS it will resolve the name.
Phones are different because they are always connected by cellular service.
I want to block users from accessing their facebook account when they are at my house "visiting".
Thx,
