My mac pro is connected to a WiFi network and internet access works normally. I've turned on Internet sharing from WiFi to Ethernet 2 and have connected an Ethernet cable from Ethernet 2 on the Mac Pro to the LAN connection on the LG Smart TV. The TV would not automatically find the connection and the Mac Pro shows a 169 IP address. Since this is auto-assigned I assumed that this was the issue. I changed the IP address on the Mac to a manual setting of 10.1.1.1 subnet 255.255.255.0 and then, on the TV I set the IP manually to 10.1.1.2 subnet 255.255.255.0 and the gateway to 10.1.1.1. This allowed the TV to pass the first stage of the connection but then it now fails on the DNS portion. I tried putting in a DNS of 10.1.1.1 (assuming that the Mac would be acting as a gateway and provide DNS services to the TV) which failed. I then tried 192.168.1.1 which is the IP of my wireless router that the Mac Pro is connected to. That failed to so I tried 22.214.171.124 (Google DNS) and that failed as well. It seems that the TV is connecting to my Mac Pro, however it can't seem to find a valid DNS server and that prevents the network setup from finishing. I don't really need internet on the TV as I only wanted to be able to play content from a locally attached hard drive using Plex's DLNA server, however it would be nice to also have Netflix access and other things in the future. Has anyone here set up something similar in the past? Anything obvious I'm overlooking? I do realize that the simplest solution would be to run a physical cable from the router to the TV, however that would involve crawling under the house again and so if it can be avoided, I'd like to avoid it and I thought that the "Internet Connection Sharing" feature would make something like this really easy. Attached are screenshots of the settings on both the TV and computer. Any help will be appreciated Thanks!
