hi,
I want to do shoutcast radio.
i have adsl modem with static ip 233.13.13.1 and internal lan interface 192.168.1.1.
on nat (adsl) i did port forwarding to my linux router(192.168.1.222)
adsl:8000->192.168.1.222:8000
my shoutcast radio on computer in internal network(10.15.0.0) with ip adress 10.15.0.89.
on linux router i have two lan interfaces (eth0 192.168.1.222) and eth1 10.15.0.222.
i have did iptables rules on linux router(10.15.0.222).

iptables -t nat -A PREROUTING -p tcp --dport 8000 -j DNAT --to-destination 10.15.0.89

iptables -t nat -A POSTROUTING -d 10.15.0.89 -p tcp --dport 8000 -j MASQUERADE

but it doesn't work.

if i try to connect to my server via linux router from my network it works well(music plaing).
telnet 10.15.0.222 8000
if i try to connect to my server via internet it doesn't work.
telnet 233.13.13.1 8000

OS cent os 5.4
radiocast ->Shoutcast

thnx
