Hi,
I’m running 6.0.2 on my Omnia.
I’ve got a device wired directly to lan4
, which is configured as:
config interface 'VERO'
option proto 'static'
option ipaddr '192.168.2.1'
option netmask '255.255.255.0'
option ip6assign '64'
option ip6hint '2'
option device 'lan4'
This device in question has IPv4 address 192.168.2.21
. In that device, if I try to join multicast group 239.77.3.6
via:
socat STDIO UDP4-DATAGRAM:239.77.3.6:8889,ip-add-membership=239.77.3.6:192.168.2.21
I can see on the device via tcpdump (with tcpdump -i eth0 -vv src 192.168.2.21 and igmp -n
) the IGMPv2 report packets to join the group:
09:22:21.516913 IP (tos 0xc0, ttl 1, id 0, offset 0, flags [DF], proto IGMP (2), length 32, options (RA))
192.168.2.21 > 239.77.3.6: igmp v2 report 239.77.3.6
However if I listen on the Omnia side with tcpdump -i lan4 -vv src 192.168.2.21 and igmp -n
I cannot see any traffic at all. Other traffic like ICMP or TCP is visible as it should.
Does anybody know why?
Thanks.
