[NTLUG:Discuss] routing problem?

[m m]

All:
 
I have the use  fedora 8 as a firewall/router.
Time Wanner basic cable connection.
Don't know what the problem, when try to download a file, it only goes to 9 kb/sec.
 
Another "big" problem is
only that fedora 8 firewall/router box can go to http://mypisd.net
the rest of my computers (connect to the internet via this firewall/router box) can't find that server (can't go that web site)
this is the error message: 
  Internet Explorer can't display the page
   ...
 
How/What can cause the problem? 
 
Again, the rest of my computers can go any other web sites except mypisd.net site.
 
Can any one help?
 
Thanks.
