Thanks everyone for your input. Sorry I didn't see any of your other posts DrillSergeant regarding IP but what I have looked at now (from your site) makes a lot more sense.

In answer to your question ARodriguez, I didn't predefine the IP address range anywhere. Just the line's as per the first post.

Anyway thanks everyone again, it's nice to see ppl helping us newbies (or not so newbies) out.
