Network:
10.1.1.2 and 10.1.1.3 in same network. 10.1.1.2 has VPN server running in bridged mode. 10.1.1.4 - ip address of VPN client. All machines have Debian 6 installed.
I'm trying to test multicast using iperf.
Listener:
iperf -s -u -B 224.1.1.1 -i 1
Sender:
iperf -c 224.1.1.1 -u -T 32 -t 3 -i 1
These combinations work fine:
- Listener on 10.1.1.2, sender on 10.1.1.3
- Listener on 10.1.1.2, sender on 10.1.1.4
- Listener on 10.1.1.3, sender on 10.1.1.3
- Listener on 10.1.1.3, sender on 10.1.1.4
- Listener on 10.1.1.4, sender on 10.1.1.3
- Listener on 10.1.1.4, sender on 10.1.1.4
These combinations fail:
- Listener on 10.1.1.3, sender on 10.1.1.2
- Listener on 10.1.1.4, sender on 10.1.1.2
- Listener on 10.1.1.2, sender on 10.1.1.2
So, I can't send any multicast packets from 10.1.1.2.

Where the problem could be?
