I had this problem a few months ago and one of the posters helped me fix it, but I forgot how he did it. I can connect on my laptop and on my iphone in wifi, but not on 3G. I tried to go into the port forwarding section, but there is no option to "add" a device. Has anyone had this problem and been able to fix this. Eferz was able to fix this for me, so maybe if he reads this, he can help me again. Thanks
If you are not able to get the remote connection, you will need to adjust some settings on your router in order to enable this feature. This thread will help you to get the forgotten steps.
