Internet connection sharing

I have a NAS running OMV5 that has 2 ethernet ports. One is built into the motherboard, one is a PCIe card. The one built into the mobo is the one that is connected to my home router, the other is unused. I am currently trying to basically setup "internet connection sharing" where I want to be able to plug an ethernet cable into the spare NIC on my NAS, and run it to my sons PC. I have tried just about every "bridge" guide I can find... OMV Web GUI doesn't really help, the systemd file creation and what not allowed my sons PC to connect, but it doesnt have internet or network access (shows as unidentified network on his Win10 system).

Any help would be greatly appreciated.

Thanks,

Corey

Anybody? I have tried doing everything in the links below:

The OMV GUI option to bridge doesnt work really the way I'd figure... Within the GUI, I can see my ethernet port enp3s0 which is connected DHCP to my router (which has it set to a static IP address) as the only interface. Clicking to add a new one, and then selecting "Bridge", I can then see my OTHER network card enp6s0, but selecting it alone doesnt allow it to provide a network/internet connection to the PC on the other end of the ethernet cable. I would expect to need to be able to select both enp3s0 and enp6s0 to actually create a bridge to pass internet connection to another computer, or what?

Regardless, nothing will allow internet/network passthrough. It shows on the Win 10 PC that his computer is connecting to an "unidentified network" that doesn't assign him an IP address or provide network access.

Zitat von gderf

Your approach is incorrect. Plug both computers into the router instead.

My OMV server sits under my sons room. It is running directly to the router (the enp3s0 port) via cat6. I am trying to SHARE internet access with my sons computer as he says his wifi is too slow. So I have dropped a cat6 line down from his computer and want to plug it into the spare ethernet port on my OMV server, enp6s0, and pass through internet connection/network access on his Win10 system.

I understand that would solve the issue... I just thought that I could save a few bucks and provide internet connection to his computer through the server, like I would be able to if it was a windows machine instead of OMV5...
