thanks Ken
I understood that, so I'm already feeling a lot better (all too often, explanantions are written in a way for people who don't need them, oh well, such is life)
I'm looking up that web now – alas my router 'manual' is non-existent, as I got a sort of minimal brochure with it from my local ip service provider (package deal story)
Thanks again, I'll post later with a progress report :-)
Ian
