I'm. It works well with IPv4 traffic, but it has not been fully tested with IPv6.

I run this code on my OPNsense router to restore sanity to my home network. Everything works fine when I send the packets on the localhost.

filter with the destination port (see Display filter) Unfortunately, this breaks things like the Roku app because SSDP isn't meant to cross network boundaries. For a class, I have to develop a socket listener for a Windows machine in C and a packet sender in Python.
It accomplishes this without assistance of server-based configuration mechanisms, such as Dynamic Host Configuration Protocol (DHCP) or Domain Name System (DNS. In older versions one can use the http filter, but that would show both HTTP and SSDP traffic. May 3 00:47:02 unknown daemon.warn miniupnpd11734: SSDP packet sender 169.254.231.147:49152 not from a LAN, ignoring May 3 01:00:11 unknown daemon.warn miniupnpd11734: SSDP packet sender 169.254.181.103:49152 not from a LAN, ignoring While this is happening the receivers are still starting up and haven't yet made DHCP requests. The Simple Service Discovery Protocol ( SSDP) is a network protocol based on the Internet protocol suite for advertisement and discovery of network services and presence information. Since Wireshark 2.2, one can use the ssdp display filter. The SSDP dissector is based on the HTTP one.
SSDP is HTTP like protocol and work with NOTIFY and M-SEARCH methods. According to that I should now be able to use NWConnectionGroup (not NWConnection, since it wasn't deisgned to handle multicast, correct) to send SSDP packets to the multicast IPv4 address 239.255.255.250 (already tried it in Playground and sending the packet works) and the receiveHandler should then be able to retrieve and show the unicast. This is clearly ANOTHER BUG in the D-Link DSL-5300 I can actually connect to my router using EITHER 192.168.1.1 OR 192.168.7.1 and login. I get 10 of these warnings every 10 minutes so my logfile fills up with this crap. The SSDP protocol can discover Plug & Play devices, with uPnP (Universal Plug and Play). My DSL-5300 also spits out these warnings 'SSDP packet sender 192.168.7.1:1900 not from a LAN, ignoring'.
