There is an additional step to enable hub functionality.
For documentation see:
The iptables rule is a requirement currently. It would be nice if nhrpd
could automatically configure kernel for this. Unfortunately hashlimit
like functionality cannot be done of PF_PACKET socket filters AFAIK.
But it is needed to not keep nhrpd scalable when shortcuts don't form
for some reason.
And at least for now, I prefer not to automatically adjust firewall
rules from nhrpd.
