Hi,

I try to receive multicast traffic, but i can´t get it to work.

My config looks like this:

interface4 eth3 LAN_DHCP
	policy return
	server dhcp accept
	server multicast accept
	client multicast accept
interface4 eth3 LAN src 192.168.1.0/24
	policy reject
	server "dns ssh ntp snmp ping" accept
	client all accept

All Packets will be blocked by the firewall:
kernel: IN-LAN:IN=eth3 OUT= MAC=01:00:5e:00:00:fb:f0:9f:c2:10:82:53:08:00 SRC=192.168.1.14 DST=224.0.0.251 LEN=87 TOS=0x00 PREC=0x00 TTL=255 ID=11337 DF PROTO=UDP SPT=5353 DPT=5353 LEN=67 
kernel: OUT-unknown:IN= OUT=eth3 SRC=192.168.1.248 DST=224.0.0.251 LEN=281 TOS=0x00 PREC=0x00 TTL=255 ID=44102 DF PROTO=UDP SPT=5353 DPT=5353 LEN=261 

When i look at the output of "firehol status" there are no rules for multicast traffic.

How is it supposed to be done, to accept multicast traffic?


Regards

Marco
