OBiON iPod Touch 4G - Sprint 3G Hotspot Issue

[FreeServiceForLife]

I'm running into a problem with the OBiON app for the iPod Touch 4G where I can successfully use the service using WiFi at home or a public WiFi, but when I try to use the service using my Sprint 3G phone as a hotspot it fails.  This is something new as it did not do this previously.  I get an error message when attempting to login to the application that says:  Error Signing In - Check your User ID and Password.  When I switch to WiFi, the app logs right in using the identical credentials.

Does anyone know if Sprint is blocking this service?  Is there a setting on my home router that may have changed that I need to look at?  I have a Motorola SBG6580 with WAN Blocking disabled and SIP ALG Enabled.

Thanks,

All, if you're having issues as I have with OBI, I did the following and it worked like a charm:

After logging into your device, go to the advanced tab, under "DMZ host" enter a 2 and "apply", you're DONE!!!  It should work.

If not, try the port trigger (option directly above DMZ host) and allow port "x", where x is the port you have your obihai device connected to.
