New toilet and soil pipe

I am installing a new toilet and have concerns about reconnecting the soil pipe from the new WC to the Cast Iron soil pipe.

Is this straightforward - do i need to consider types of materials when connecting the from ceramic to Cast iron?

I dont think there are any other concerns other than the connection itself and the proffesionalism of the job. I am capable of general DIY but is this beyond the limit of normal DIYers.

Can someone help?

Thanks

this what you mean

Kevplumb,

Thanks for that! Is this all i need?

Is it difficult to make the connection?

Cheers

push the black end inside the pipe and attach toilet pan to other end
