What are you trying to accomplish?
Have the Tablo at home, and be able to remotely connect to it from work, and other places outside your home network?
Or, have the Tablo at work, and be able to remotely connect to it from home, and other places outside your work network?
Whatever network the Tablo is in is the one that needs its router set up to forward Tablo Connect ports.
So, if the Tablo is home, then the home router needs port forwarding set up.
If the Tablo is at work, then the work router needs port forwarding set up.
