How to access NW Portal from out side the server?

Hi,

We prepared one Neweaver System for MES(Manufacturing Execution System)

on SAP NW 7.3 ehp1 environment and the installation and post-steps were

completed and we are able to accessing the system within the server by

using http://<hostname>:50000/NWA and for MII we use

http://<hostname>:50000/XMII and ME

http://<hostname>:50000/manufacturing/index.jsp , everything is fine

here

at Server Level.

But while we trying to accessing it from outside the server its not evenpossible, we assigned one public ip to the server and opened the

firewall

at server level(i.e Disable the firewall settings) and created one sub

domain for the ip(public ip which is assigned to the server) as

<sid>.domain.com but no one working.

Could you please help us to get this error fixed,Appreciate your time and help.

Regards,
