Rikkitic:Do you mean VDSL? Anyhow the answer is no. :)
I finally got this working on my identical device at home so I should be able to do the same the next time I am at my friend's place. I just wasn't going far enough into the settings. As a temporary fix, I changed the setting in the router but can put that back on my next visit. Thanks everyone for the help.
Another question: I believe my friend has been upgraded to VDSN and IP allocation is now dynamic. I remember reading something about this awhile ago. Does he need to request a static IP from VF in order to be able to use an external DNS server?
