Hi,
I have two VLANs, VLAN1 and VLAN2 each on their own subnet, with a pfSense firewall at the hub.
On VLAN1 are a number of consumer devices, and on VLAN2 are a pair of OMV4 systems with mini-DLNA installed. mini-DLNA uses two ports:
- TCP 8200: I assume this is the direct media transfer port, and so we only need a rule on VLAN1 interface allowing TCP traffic to destination on VLAN2 subnet port 8200.
- UDP 1900: This is apparently the UPnP service discovery port.
The UDP is the part I don't understand how to configure.
- Do I need to allow port 1900 through the interface of VLAN1 and/or VLAN2?
- Is the destination the subnet of the other VLAN, or the broadcast address (I believe this is 239.255.255.250)?
- I thought a UDP broadcast could jump between subnets, is this the case? If not, what do I need to do to permit it?
- Some posts talk about IGMP, is this even required? Do you not just need to permit the UDP broadcast?
Any help would be appreciated.
Regards,
Rob,
