Calm down Mark, part of the CCNP is about planning and designing ... by now i would already be jacked into console port of my core router and have thrown a tonne of config at it!

One step at a time, iv made a note, a quick diagram and lets plan it and think about it, "not on the fly" usual stylee!

So ultimately create 2 VLANs, 1x LAN, 1x WAN, have RAS VPN, and additionally not on diagram a GRE tunnel routing EIGRP over to the works ADSL NTE ... DRRROOOOoooool

Right onward with study!
