Allow all rule for one interface using firewalld

I have two interfaces in my CentOS-7 VPS. I want to allow all access to one interface(eth1, that is my private network). I'd change zone of eth1 to home how can i add a rule to allow everything on that interface ??

The natural way is setting the right target to your zone:

firewall-cmd --permanent --zone=YOUR_ZONE --set-target=ACCEPT

Set the target of a permanent zone. target is one of: default, ACCEPT, DROP, %%REJECT%%

You can use Rich Rule concept of firewalld for this. Try following rule :-

firewall-cmd --zone=home --add-rich-rule='rule family="ipv4" source address="0.0.0.0/0" accept'

Check your rule :-

firewall-cmd --list-all --zone=home
