How to get passed the filter?

I'm currently on a ship, it has Wi-Fi but there's a filter on so I can't access adult material.
Anyone know if I can get passed this? I'm on an IPhone using the Wi-Fi by the way.

You probably can't unless you have access to a computer. Can you change any proxy settings?

You can't and you don't want to try. You can be responsible for all sorts of fines if you monkey with network security settings. You really don't need adult material anyway.
