Need some help setting up multicast on an Archer C7 v2, which has
eth1 = lan and
eth0 = wan. The eth1 MAC shows as LAN.
ptp4l -i eth1 -m -S
And it does its thing. It multicasts/broadcasts to e.g.
224.0.0.x when you also specify
-P. The specification mandates as follows:
|IANA assigned name||Address|
Enable multicast support are checked under eth1, wlan0, wlan1 devices (default).
When I run tcpdump on eth1, I see traffic from my WAN IP bound for the multicast networks, instead of the expected
192.168.1.1. tcpdump on eth0 confirms it does not egress there, and tcpdump on br-lan confirms it does not egress there. Local workstation pcaps also confirm this. The pcaps show the LAN MAC but the source IP is the WAN IP....
route add -net 22.214.171.124 netmask 126.96.36.199 br-lan and
route add -net 188.8.131.52 netmask 184.108.40.206 wlan0 etc from the wiki. No joy. Tried also more specific:
route add -net 220.127.116.11 netmask 255.255.255.255 wlan0
What firewall or other magic am I missing, to steer these broadcast packets to the br-lan? Do I need to make a new bridge in DSA?
Edit: tried the recommended options
Multicast to unicast for
eth1 but still nothing.
