I have a wpf app that needs to communicate(exchange data) with a custom designed device (we can modify the code for the device). Do I have any options to connect to the device if it is behind a firewall via http? I was hoping there would be a method where the admin would not have to forward any specific ports or do anything on his end. I assume the issue is how would I address the device from my app. I know SOAP over SMTP is one option. Is another option where the device could chatter out to my application via http?

    UPNP is supported by some firewalls to simplify this. Otherwise you are usually stuck opening ports on the firewall manually or using some 3rd party proxy server for a rendezvous server.
