I am running Ubuntu 16.04 and I am having trouble sharing my wired internet connection with my SmartTV.
My setup is a single on-board Gigabit port (enp3s0) and a separate 100Mbit PCIe card (enp6s0).
The enp3s0 is connected directly to the RJ45 socket in the wall. It connects with DCHP and works flawlessly.
I wish to allow the SmartTV, which is connected via a cat5e cable to the second NIC enp6s0, to have full access to the internet connection.
The TV is a Samsung UE55HU7500. It's quite limited as to what settings I can change regarding networking. I can set it to "Get Settings Automatically" or enter the values for IP Address, Subnet Mask, Gateway and DNS Server.
Setting it to Automatic and connecting the TV to the wall works fine. I know this can be fixed with a switch, but right now that's not an option.
I have been trying for a while now but my limited networking skills are not really helping. Hopefully someone can provide me with a simple explanation of how to get this working.
