I stopped iptables and tried it again.... no change.

Something I did notice though in examining my router firewall logs....

My firewall is blocking a lot of traffic from my ISP DNS server... 
specifically udp traffic from port 1078.

According to http://www.iana.org/assignments/port-numbers udp port 1078 
is Avocent Proxy Protocol.

What the ?? Shouldn't DNS replies be coming back to me from port 53 
(domain)?

I wonder if my ISP reconfigured something recently that's causing me 
grief... wouldn't be the first time.

Aye chihuahua!! :-)
