Comment (by braveheart_leo@…):
I just want to add some further observations and tests I have conducted.
As previously mentioned, packets are arriving at the wan2 (eth0.2)
interface, seen from a tcpdump, but they are not hitting iptables,
indicating that the packets are being dropped early on:
{{{
Chain delegate_input (1 references)
pkts bytes target prot opt in out source

18 1754 ACCEPT all -- lo * 0.0.0.0/0

0.0.0.0/0
0 0 DROP all -- * * 0.0.0.0/0
0.0.0.0/0
}}}
Also, if I issue `ifdown wan`, then wan2 starts working, forwarding
packets to and fro.
