My cellphone provider, T-Mobile, sent me a CellSpot to help with my reception. It's connected via my internet gateway via ethernet cable.

Their tech support says I need to open UDP ports 123, 500, and 4500 on my internet router.

I've tried,, among other google results, but when checking on my computer via those ports are still closed.

Any ideas?
