complicated router question....

[kyle]

Hello all,
I have recently installed dsl at home. The dsl company
is very restrictive about stuff and they wont give me
the password to the dsl modem for administration... I
have an ip masq server connected to the modem (pppoe)
running to get all my computer on the internet. Now my
question is how can i or can i run any type of server
on my home network? I do not understand how i would
set it up to say run a web server that people could
reach from the internet. But then if nothing gets thru
how is it that stuff like bearshare and icq works?
Thank you an advance for helping me understand what i
hope is a basic concept :)
-Kyle
