    I've got peer-to-peer internet sharing set up on one of my Macs, which I use for wireless devices, including iPad. The main network is LAN based, with wired cable modem and wired router.

    OS 10 (Mavericks) does not automatically route the wireless network to the LAN. How can I accomplish this, so I can access all Macs on the LAN from my iPad?

    Go into System Preferences > Sharing and enable Internet Sharing (share ethernet connection on wifi). That accomplishes what you want. Not sure, but I think the regular ad-hoc wifi network is separated from other interfaces.

    Thanks for the suggestion.

    When I added ethernet to the internet sharing I got a warning from the OS saying it might disrupt my connection to the ISP--and it did.

    Completely futzed the networking on the sharing Mac--couldn't get in or out.

    Don't know if what I want to do is possible, but here's some more info.

    I have an old Mac Mini on the network being used as a music server. I want to be able to VNC into it from the iPad to control iTunes. The Mini does not have wireless.

    Right now, I can do it, but I have to chain it first by VNC'ing into the peer-to-peer sharing Mac (via wireless), then creating a screen sharing connection from that to the Mac Mini over ethernet.

    This creates a pretty clumsy UI.

    It would be ideal having a route to the LAN from the wireless network thru the sharing Mac--but maybe it isn't possible.

    Alternative is to get a USB wireless adapter for the old mini; and of course, a newer Mini with wireless would also do it.

    Hmm, you shouldn't be having that problem. You told it to "share your connection from ethernet" and selected Wi-Fi in the list below, right? The Internet Sharing warning isn't about technical limitations, if I understand correctly. It's to tell you that your ISP might shut off your access if you violate a EULA or something by sharing it. For example, some paid ethernet connection at a hotel might be for one device only. I assume you're not in that scenario. If it's not working, I don't really know what could be the problem.

    The second option you described is a pain. That's what I used to do when I wanted to connect to the Mac mini server from school, going through my iMac (which was open to WAN connections) first... using a VNC client on an iPod touch, haha.

    Besides getting your mini a wireless card, you could get an Airport Express or some other wireless switch to share the wired ethernet connection over wifi as a last resort.

    We have a similar problem where I can't route traffic from the LAN to the Wireless network and back.

    All our Mac's wired through various thunderbolt, USB and internally connected NIC and use a common WiFi network. No matter which machine we try, including an air port, sharing the connection does not allow bridging between the two networks. I think it might be because the WiFi is secured with WPA2 and therefore the unsecured LAN is prevented from connecting (as it would effectively allow any computer on the LAN to access the WiFi). Has anyone else come across this or is it just my imagination?

    Also, our printers and Mini are all on the LAN and we can't connect to them unless the LAN is at the top of the Service list in Network preferences. However, the Internet access is through the WiFi connection and does not work unless the WiFi is at the top of the Service list. If I unplug the Ethernet then the WiFi works fine and if I turn off the WiFi the LAN works fine - but not both at the same time! Any suggestions on how to make them both work at the same time - Route? DNS?

    You mention airport, do you mean airport extreme or airport express?

    Try repairing permissions and reboot the computer.
    Are you using the access control feature on the AirPort Extreme?

    No restrictions are set but I tried bridging (internet sharing) on the Mac Mini again and got this:

    Your Internet connection cannot be shared because it is protected by 802.1X.

    See attached screen shot. So I think my original premise may be right in that if the WiFi is 802.1x (WPA2 Enterprise) it can't bridge (or share) the connections.

    Have you tried on the Mac creating a computer-to-computer network (WiFi->Create Network...)? This is essentially creating a hotsopt.
