Do mobile networks (cellular networks) these day commonly allow anything but TCP? (or even HTTP? Most firewalls block anything that is not HTTP/HTTPS)

- anilgulecha 10y agoDon't see why not -- many popular VoIP protocols run over UDP.
- otoburb 10y agoCarrier firewall policies generally allow any outbound traffic. Some carriers in specific countries may have more restrictive policies for either regulatory or carrier-specific reasons, such as the United Arab Emirates Telecommunications Regulatory Authority mandating all VoIP services obtain licenses[1], resulting in specific blocks on VoIP traffic such as Skype, WhatsApp, Viber, etc.[2].

- azylman 10y agoLots of video games (including mobile) use UDP so I'd be very surprised if mobile networks blocked UDP.
- clarry 10y agoIn Finland, the big operators use CGN by default. So if it works, it only works as a one-way street and p2p or hosting your game at home is no-go. At least one operator allows you to lift the restriction though. With money.
