Hi Jeff, As Stuart and Simon pointed out, this is not how you should do it. You need to get a bigger slice e.g. /56 from your provider to subnet your internal network with. Your /64 should only be used on the network between your operators GW and your GW.
Alternatives: 1. Get a /56 from Comcast 2. Get a tunnel from sixxs or HE (which will assign you a /56) It might also be possible to run your GW in bridged mode, havn't tried that myself though. Comcast probably assumes that you should put all your gear on the network without a GW.. Good Luck, /joakim
