Due to Chorus and Vodafone not being able to organise a pissup in a brewry im at the position where i need to send a cat6 cable from the ONT in the properties main house to a self contained attached flat. The onyl way to do this is through the plaster fire proof wall. This isnt something that cant be done considering power and sat dish COAX does this but what im after is all the seperation requirements between penetrations and what sealant needs to be used.

Any help would be awesome.
