@Tomaq Before you made a change to o2 cable. Did you need a public IPv4? 
o2 cable provide only DS-Lite.

I didnt change anything yet, just asking if its possible.

@Tomaq Yes it will been possible, but there may be problems with VPN / home office because of the lack of public IPv4.

Wait for an o2 moderator how can made an offer for you. Did you want a rented cable Fritzbox from o2 or buy yourself a router?

Hmm i was not aware of the issues with IPv4.

Might have to reconsider moving to cable then.

I dont wanna make a change at the moment, maybe in the future.

Thanks
