umm... i think you got me a little lost :p

my server is at 192.168.123.456
my surfing computer is at 192.168.123.457

the router forwards to port 80 like it should.

when my dad (out in az) connects, 71.71.789.456 he doesnt have a problem in 
the world

when i connect to my server71.71.789.456, i get like 6 min load times on a 
300k image.

when i connect to my server internally, 192.168.123.456, i get instant 
loading of the same pictures, or different ones that have not been cashed.

my question lies in the why cant i get as fast with the 71.71.789.456 
connection?

i know when i was liveing at home, we were useing a linksys router... or was 
it a dlink?  i had an address jsnthegod.no-ip.com

with that address i could connect with fast speeds inside the house, dad 
said the router was noticing that it was an internal connection, and thus, 
just passed it around in the internet instead of leaving the network.

now, it seems to be leaveing the network. and getting confused comeing back 
in (or this is my best guess)

of course, im more of an expert than him at this time, so he could have been 
wrong in his assesment
