WAN configuration for modem setup

[Frizzer107]

I'm currently trying to set up my modem (Zyxel VMG1312-b30a) for my new internet connection. It initially couldn't get an internet connection, so I followed the user's guide, which told me to add a new WAN configuration in the modem's web interface. The problem is, I now have to fill in tons of stuff (as shown in the screenshots below) I know absolutely nothing about, so a bit of assistance there would be much appreciated.

FYI: I live in Germany and the ISP is o2, if that is of relevance.

 

Thanks in advance!

Before replacing your ISP-provided router, always contact your ISP to see if they'll allow it and what models are compatible with their network.

 

At this point, I'd advise you contact O2 to find out if they can help you here. They're the only ones who'll be able to give you the relevant settings to gain access to their network.
