(There's no help manual for it unfortunately, so I don't know how to use it)
Could I use this application to forward specific ports back home to my router which then translate those ports back to what they should be to go to the Steam network. Is this possible? Just an idea, not sure about implementing it but I was curious.
If this idea wouldn't work, what would? maybe a VPN back home and from there to the Steam network?
Also, I'm not sure how to set it up if it does work.
As much as I sympathize with your situation, what you are asking is technically hacking by trying to bypass employer safeguards. This violates the forum policies here, so I cannot help you.
