Port forwarding in routers normally only work for traffic coming from external IP addresses, it will not work if you are logged on internally, that is why your Ipad when connected to 3G works, it is an outside access.

Is there any way around it?

Thanks for the help everyone.

at first i thought i could connect back to my LAN through router using the WAN (external address) because on connect, data was being returned,,,,,,,,,,but, unpluging the WAN cable to router, the data STILL continued comming.....meaning the router itself looped the connection back without exiting the LAN......
looks like real external testing needs external sourcing.

I have a hosting space. Is it possible to have some kind of arrangement like some kind of code or something which can listen to the incoming data at some port and then redirect it to the routers external address at specified port?
