1.8b Development

Not 100% sure I should post this here, but since I am running a beta version I'd figure I post here first.

I am running version 1.8.1b546 and am trying to get Apple Home Sharing to work.

My Soekris 6501 has Opt1 and Opt2 bridged to LAN.
On LAN a Apple Airport Extreme is connected, which is set to Bridge Mode.

The Mac Mini (with iTunes, which I want to connect to via Remote on the iPad or iTunes on another Mac) is connected on Opt2.
From another Mac that is connected to a port on the Airport Extreme, I can share the Mac Mini's screen.
This also works with a Remoter app on the iPad just fine.

Connecting the Mac Mini to the Airport Extreme makes the Mac see the shared library in iTunes from the Mac Mini.
But when I want to connect to shared library when the Mac Mini is on the Opt2 connection, I get a timeout.
The Firewall log shows a Deny from the Mac Mini on TCP 3689 (one of the two ports needed from Home Sharing) to the Mac on a much higher port number (dynamic).

That to me seems kind of weird, as the Rules show that on LAN anything if passed to anything.
Same goes for Opt1 and Opt2.

I tried setting up some rules, but that didn't work.
So I probably did something wrong there, but just got no clue what.

Really hope someone can help me out here.

I plugged in a computer to OPT2 that needs to get a IP address via DHCP from the DHCP server on OPT1, but isn't allowed too.

Lines I see in the Firewall log are:

Code:

If Source Destination Proto
OPT2 0.0.0.0, port 68 255.255.255.255, port 67 UDP

Have you enabled any rules on any interfaces that might be needed to pass the required traffic?

No, I haven't because the default rules on each port allows all incoming and outgoing traffic.
If I would need to set up rules to allow something, I would need to set up a rule for allowing VNC traffic too.
Yet, that one works fine.

Btw, I updated to build 556 but haven't tested yet.
And since there is no changelog on 556 yet I don't know if it might resolve anything.

I am not sure, but it may be that broadcast traffic can't be passed across interfaces.

That would explain why DHCP won't work, but not normal TCP or UDP traffic.
Or specific TCP and UDP traffic.
