Hi folks. - I'm stumped! - I posted this in the Yosemite sub forum, but thought I'd have a punt here too. Just got a NAS and have the following set up... Mac Pro running 10.10.3 connected via 5ghz wifi to router. Router is allocating IP addresses via DHCP. Works fine. Other wifi clients on the same network can see the Mac Pro fine, as can other clients directly connected to router via Ethernet. I want to add the NAS to the network by connecting it to my Mac Pro by Ethernet. I need any device on my wifi network to be able to access the NAS, and I need the NAS to be able to access the internet I've connected the NAS to one of the Ethernet ports on the Mac Pro. I've gone to sharing and selected share my wifi internet connection with the correct Ethernet port - turned internet sharing on - but nothing... It doesn't seem to be allowing the DHCP server on the router to assign an address to my Ethernet port or to the NAS. If I disable my wifi on the Mac Pro - I can connect to the NAS server but as soon as I turn the wifi on I cant connect to it. Any ideas anyone?
