The two nodes involved have adresses 10.0.0.1 and 10.0.0.3. When I aply in 10.0.0.1 the rule
iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP
I expect to reject all traffic in this node, am I right? Whith these rules, in node 10.0.0.1, in the interface adhoc (wifi) after these rules been applied, the packets I see with tcpdump -i adhoc are:
IP 10.0.0.3.4551 > 224.0.0.142.4551: UDP
Should'nt these packets been rejected/blocked in node 10.0.0.1? IBR-DTN is not running in 10.0.0.1, but running in 10.0.0.3.

Hey,
I think without (a lot of) further details nobody here might be able to help you. When you reply, try to supply as many relevant information as possible and needed, e. g.,
- what is the exact IP (i.e., IPv4 *and* IPv6) config of your interface(s),
- what *exact* packets do you see in wireshark? protocol names, ports,
addresses (again IPv4 *and/or* IPv6?), packet types, etc., or even the actual trace,
- possibly even your network config, routing tables, anything modified
with sysctl, and so on.
In your initial mail, you wrote a set of ip(6)tables commands. I noticed, that only 1 out of the 5 pairs is for ip6tables - have you, e. g., tried also blocking IPv6 multicast traffic? This seems at least to be missing from your provided commands.
