[TriLUG] apache cable modem woes

[r.wheaton]

Hello,
    I recently just moved out to Colorado from north carolina, and have 
been taking a lot of pictures with my dig. camera.  I have been posting 
them on my delegated 10MB through my AT&T cable modem account.  Well, 
that space has run dry.  And, what i'd like to do is just host them 
straight off my cable modem.  I've noticed that my IP doesn't change 
that much, and with the help of dyndns.org it seems like the best way 
for my friends and family back home to see my pics.  Well, I got it all 
set up, and I can see it fine, but no one outside of AT&T can.  Is AT&T 
blocking this traffic somehow??  I read on their site that they don't 
want you to host any type of server, but this seems kind of ridiculous. 
 I can understand if I was getting mass amounts of traffic, but this is 
very small.  I sucessfully did this fine from my timewarner cable modem 
when I was back in NC and it worked great.  

So, I guess what I'm wondering is, has anyone seen anything like this, 
or does anyone know of a way around it?  I tried to simply just run 
apache at a different port (8080), but still to no avail.  Thanks in 
advance.

respectfully,
