Hello,
I have setup the PPPOE on my 3620 router. But I am having some problem with my DNS, my DSL service is through Verizon, the way I have setup before with the Linksys router is working fine, the Linksys router will automaticlly obtain the IP address and DNS server IP address with NAT as well. Since I setup with my 3620 router, some URL is working fine and some is does not (like CNN.com or cisco.com). with PPPOE setup, I do not get the DNS ip address, so I manually set it in my DHCP config. But still does not working right. Anyone has same problem as mine ? Thanks for your response. Here is my configuration.
