17.1 Legacy Series / Multicast Routing
« on: March 19, 2017, 06:00:12 pm »
Hi guys,
I am having issues routing multicast traffic. I have igmpproxy running, IGMP is working like a charme.
There is UDP multicast traffic coming inbound on my WAN2 interface: igb0_vlan8
This needs to go to my local client sitting on my "MAGENTA" network (interface igb2).
Yet the tcpdump shows nothing:
I have the following rules in place:
WAN2
And wide open on MAGENTA:
Where the aliases are
Help is appreciated...
Thanks, Tobi

Code: [Select]
tcpdump -i igb0_vlan8 -v -n udp and port 10000
