Performance-wise it might indeed be wasteful. However, you never know if in future that same server might get some other functionality you don't want to expose to the said subnet. This case, however, is not similar to yours (filtering based on both physical port and IP address): in "my" case filter is only very specific (narrowing down possibilities) - but in this very particular case it may not be necessary to be that very specific. In "your" case, both filter criteria (physical port and IP address) are, strictly speaking, not related at all. Specifying both might narrow down the possibilities (possibly breaking L2 network in unlucky case) or it may broaden possibilities (in another unlucky case).3. Use of protocol and ports is a good idea in terms of limiting the ports and protocols allowed by the originating LAn to hit your server.
(seeing as there is no other functionality of the server, I tend to think that this simply wasteful as well unless someone can point out why otherwise ???

You will also need to open few rules for RTP (audio)Hi,
I have configured several Subnets on my RB3011. All Subnets cannot see each other, it is disabled by FW-Rule.
Now I would like to configure some exceptions. I have a local SIP Server on Subnet1 with IP: 192.168.1.10. Client on Subnet1 can connect correctly to the Server, but Clients on Subnet2(192.168.2.0/24) do not work. This works as expected.
How do I have to configure a common rule for Subent2 to get this working? I think I have to route UDP-Port 5060.
Can some help here?
Hi Christian -@RackKing:
Yes, My Sonos Speakers are in VLAN30 and the controllers are accross different Subnets.It works for me, but sometimes it takes some time until a controller finds the Sonos players (especially the Android widget). For updates it is recommended to join one controller to VLAN30, otherwise you get errors. It is not really perfect!
Aditionally to the rules, you need to install PIM on the router in order to route Multicast.
I have round about 15 Sonos players/bridges on the subnet and It is difficult to notice improvements. But in my view, it seems to be more stable because players disappear less often then before.
For now, VLAN30 is also participant of "VlanFriends" and there are not really restrictions between "Player" and "Controller" Subnet. There is room for improvement regarding the routing. I am open for proposal
