I recently added a wireless 802.11n router with gigabit LAN ports to my home network. Since I was not able to make the thing (TRENDnet TEW-633GR) work as a bridge, I installed it as a router on its own little subnet (192.168.0). My desktop (Hackintosh) sits on the 10.0.0 subnet (routed by a linux box with internet access) and I added my Airport Express to the network created by the TEW (192.168.10). My old G4 PowerBook did not seem to like the b/g/n mixed mode of the TEW, so I am using the AX for it and switched the TEW to n-only, which works well for the new MacBook Pro. Sooo... to make a long story short, everything works with the exception of Airtunes from my Desktop. I can see the AX and the Airtunes speakers, but nothing else (no configuration access and iTunes gives up switching to the Airtunes speakers after a minute or so of trying).
Here is an attempt at an ASCII drawing:
(Internet)---|Linux Box|- 1 --- 10.0.0 --- 200 -|Desktop| `- 1 --- 192.168.0 --- 2 -|TEW|- 1 --- 192.168.10 --- 200 -|AX|- 1 --- 10.0.1 --- 2 -|G4|
- The Linux box was told to route 192.168.10 via the TEW's 192.168.0.2 IP.
- Routing for the 10.0.0 and 192.168.0 networks worked out of the box after configuring the two virtual interfaces.
- All hosts on all networks can access the internet.
- The AX was put into the TEW's DMZ.
- Pings from the Desktop to the AX are seen on the linux box and are logged as going in and out of the correct devices.
- The TEW's log does not show any blocked traffic to the AX
- Due to wiring limitations, it's near impossible to have the Desktop and the AX on the same subnet
