(wow, the first time I hit the send button before I even had finished the
subject...)

The topic came up a few days back, when I wanted to put my wireless
devices in a DMZ. Following instructions and faq I opened udp/tcp port
3483. But this was not enough. SB1/SliMP3 did not connect at all, SB2
showed a working player interface but did not play. I had to add 9000
("web interface"), too, to get the devices to play music.

Another problem with the devices using port 9000 is that I can't block it
on the unsecure network. And if I don't, access to the server's settings
will be exposed. Not really what I wanted.

I'm quite confused about this as I never saw port 9000 mentioned in the
player's context. The slimproto documentation has one mention of it in the
"Server -> Client Communication" part. But it doesn tell a lot.

Which ports are really needed for SB? SB2? SliMP3?

Michael,

SB1/SB2 uses:
9000 is used for the streaming connection.
3483 is used for the slimproto control connection.

I think SLiMP3 uses UDP on 3483 but I've not really looked at that.

What access point are you using? Can it do fine grain filtering? [I have a WRT54GS running Sveasoft software also acting as a
firewall configured by fwbuilder.]

I always thought 9000 was the web interface and stream.mp3 only.

It's a local "brand", but I think it's a rebranded Trendnet wlan/router
(the cheapest I found...). But this is not even important: the "DMZ" ->
LAN routing is done by a Linux machine. I added rules for these two ports
and locked down access to http accesses to the three players (in
slimserver).

How fine is fine? It's fine enough to only allow my music players to
access the DMZ from the WLAN. All other devices (guest's laptops) only can
access the internet. All in all this should be secure enough for my needs.
