I want to access my Desktop computer via my Public IP (Got via 'My IP' )
But I can only reach my Modem settings screen.

I tried DDNS setup and now my modem settings are displayed with the DDNS weblink.
How can I access my computer.

I have a CGI application running on port 8181 for testing purpose on my Desktop Computer.

Does your modem have a built in router/firewall?  If yes then you will have to open up port 8181 and forward that port to the IP address of the internal computer you're trying to connect to from outside.  Go to the port forwarding option on your router/modem.  What make and model is your modem/router?

I tried disabling the Firewall for a short while but yet it did not allow.

Did you configure port forwarding (Static NAT) on your router.
eg port 3389

Assume Public IP is
Anytime you access remotely, the traffic will be forwarded to your computer with IP on port 3389

I cannot find a manual on how to do port forwarding for your specific router.  Perhaps, it's the same at this other model.  Have a look as it may be the same:
