I have ADSL router with public ip address, I did the port forwarding for port 80 to redirect to IIS in a web server in case client put my public ip address in his browser and its working fine.
now, the company brought another device which can be controlled and configured in a web portal,
so when I click 192.168.1.75:90 I can view the web based application for that device,
my manager asked that he wants to view this from his home, so when he just put the public ip address and port 90 he would view the web portal of that device ((98.45.x.x:90))
I did that but its not working, I couldn't view the web application of the device, but its working fine for port 80 !
((98.45.x.x:80)) is working and pointing to iis server but ((98.45.x.x:90)) is not working!
so how can I solve that?
