Restore iptables at once using iptables-restore instead of calling iptables numerous timesThis makes handling the firewall rules about 50-60 times faster because it is generated in memory and then loaded once. It's work by @borisroman see PR #1400. Reopened it here because I think this is a great improvement.
* pr/1482:
Resolve conflict as forceencap is already in master
Split the cidr lists so we won't hit the iptables-resture limits
Check the existence of 'forceencap' parameter before use
Do not load previous firewall rules as we replace everyhing anyway
Wait for dnsmasq to finish restart
Remove duplicate spaces, and thus duplicate rules.
Restore iptables at once using iptables-restore instead of calling iptables numerous times
Add iptables copnversion script.
