Works with LAN but not with internet

firstly , im a bit of a newbe so all help is apreciated

ive got windows server 2003 running windows media services

ive got it to broadcast a playlist of songs , ive then got a embedded player
in my website ,

it wokrs ok over my LAN using the address that the announce tab in media
services gives me which is

mms://SERVER/music

so i tried to get it to work over the internet , i read some forums that it
needs ports forwared on the router

so ive forwareded the TCP port 1755
and the UDP Port's 1024 -5000

im not sure what else there needs to be

obviously i was going to need my public ip to connect which is 86.28.146.142

so i gave that a try and the addresses ive treid are as follows

mms://86.28.146.142 ( doesnt work)
mms://86.28.146.142:1755 ( doesnt work)
http://86.28.146.142 ( doesnt work)
http://86.28.146.142:1755 ( doesnt work)
86.28.146.142 ( doesnt work )
86.28.146.142:1755 ( doesnt work )


The firewall on the server is DISABLED so the ports arnt being blocked there

if i connect to in the embedded player

the message goes " connecting to media " " ready " and does nothing
