Hi all,
When creating a new network:
1)
Is there a way to disable automatic spawning of dnsmasq on network creation? I read that leaving out the <DHCP> section should accomplish this, but that is not
what I am seeing.
2)
Is there a way to disable automatic installation of iptables rules?
3)
For that matter, what is the purpose of the default iptables rule set? Doesn’t line 3 let all traffic pass anyway?
Thanks,
Paul
