Hey lawman508,
Thank you for reaching out! Opening up ports are not supported. What you can do with the Hitron is to enable a secondary IP for an IP passthrough, this should open up the port or you can connect a third party router that supports this specific feature. You can find the steps on how to set that up here. Hope that helps. Otherwise, others in our Community may chime in on this subject.
Cheers,
