adelphia blocking www

[deadpoint]

hello,

i've noticed that adelphia is blocking traffic to port 80/http so people 
can't connect to personal webserver running inside there network. so i 
figured that i'd do a little port forwarding to get around this yet i'm 
still unable to get to my site. now i don't think that i have anything 
misconfigured in the ipchains rules but i'm look for some clarification.

i'm run coyotelinux 1.3.something with kernel 2.2.19. i've flushed all 
existing ipchains rules and ipmasadm rules so all i have is the 1 portfw 
rule. the site is www.darins.net

coyote# ipmasqadm portfw -a -P tcp -L `getifaddr eth1` 80 -R 192.168.0.3 
6000
coyote# ipmasqadm portfw -l
prot localaddr            rediraddr               lport    rport  pcnt  pref
TCP  ny-niagara6a-b-23.buf.adelphia.net 192.168.0.3               
www     6000    10    10

any ideas or thoughts on this?
