Strange problems accessing Netflix images



The Netflix website comes up fine, except none of the images come up. 
This is true ONLY for netflix, and true for every computer in my house. 
  And this just happened a few days ago (I've been a member for years).

Note that the images come from cdn-*.nflximg.com (208.111.128.6 and 
208.111.128.7), not netflix.com.

If I try to wget an image, it hangs.  Looking at Wireshark as I do so 
shows a bunch of outgoing packets, but nothing coming back.

If I traceroute it, I get two hops, then stars for the next 26 lines

I checked my cablemodem (SMC-8014), and it doesn't show any website 
blocking, etc.  When I use the web-based interface to my cablemodem to 
traceroute it, I get

It sure looks to me like my cablemodem can reach it, but my server 
can't, and I don't know why that would be, since my firewall doesn't 
report anything.

Any thoughts?  Thanks.
