Help with PIC+Internet project

I have gone through endless options in Norton Internet Security to allow port 5578 (External port) but could not find any option. (Using windows 8).

I tried sending the data through my ipad app internally (internal IP of laptop rather than external IP or router) directly to port 5579 (Internal port being monitored currently on laptop) and data did arrived. DO you still think it is a problem of firewall? As it does work internally but when sent to external IP of router it does not arrive. Could it be a setting on router, not opening the port 5578?

Thanks

Thanks. The problem is HALF solved.

I get the data if it comes from another place, I mean--> I switched on my phone's 3G connection --> I connected my ipad to internet by creating a hotspot through my phone --> I sent the data through the app to my router's external IP and this time it showed up on my laptop.

Why is it not coming when my iPad is connected to the net through home wifi?

seems like it... is external port 5578 or 9 and internal port 2500, then net assist should be listening on 2500

Sorry for the confusion earlier. As I kept experimenting, I kept changing the ports as well. For now, external is 5578, internal is 5579.

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?
