smoothwall 3.0

Hi Guy's and Merry Christmas to you all. I have just installed the smoothwall 3.0 and want to use a speedtouch 330 modem as my red interface but i cannot seem to find the drivers anywhere i do find driver's from the link within its web interface however when i upload them to the smoothwall it stats they are incorrect i've googled this and tried quite a lot of drivers but none seem to be doing the trick. Does anyone know where i can find the correct drivers?

I know this may seem like an obvious question, but why don't you save yourself a load of hassle and pick up a cheap modem router?

At the time i posted that was all the hardware i had and being Christmas time i'd a million things to do and was hoping someone had a direct link to the correct drivers resulting in a quick response. Anyhow since then i did exactly as you said and everything is now running fine.Thanks for the reply.
