Wireless Router Problem

Hey,

I was using CV Michael's SendFileWinsockProject, and found that, while i could send files to my laptop, which has a wireless connection to a router which my main computer is plugged into via a lan cable, i could not send files back. It acted as though it simply couldn't find the server App.

Any ideas?

Hi,

I'm not familiar with the code you're using but the problem sounds more like a NAT issue in the Router or a firewall issue which is blocking unsolicited requests to the server. ie the server can send to the laptop Ok but the laptop is being 'blocked' by something when trying to do the reverse. If the router is performing some NAT you will probably need to look at the configuration to find out the 'proper' IP address to use for the server. It may help to look at the Winsock.RemoteHost property in the laptop when you perform a successful transfer to the laptop.
