As per my other recent postings, I run a Draytek Vigor120 modem currently in standard modem mode behind a Netgear WNDR4500 wirless router. I'd switch to PPPoE pass through mode, but the downside of that is losing the web interface to the V120. Conversley, the downside of sticking with the standard modem mode is that I'm double NATing.
The question is whether double NATing is (i) a significant / fundamental / performance degrading problem that ought to be avoided if at all possible, or (ii) something I needn't worry about in everyday domestic use with a few wired and wireless devices around the house being used for web browsing, emails, Skype VOIP and the occassional media streaming?
Is there a clear answer on this, based on which I can make the decision in which mode to run the V120?
