Reset Firewall from CLI

    Hello,
    I have a problem. I configured my OMV firewall like in the guide here in the forum, but I changed the source and target IPs, because the IP of my NAS is 192.168.178.10 and my IP on my PC is 192.168.178.25.
    So I made for source 192.168.178.0/24 and for target 192.168.178.10.
    But now I have the problem, that I can't access the webGUI any more, I think the firewall blocks it. I still have SSH access, because there is no source and target mentioned (in the rule).
    My first question is: How can I reset the firewall via CLI (/etc/network/if-pre-up.d/iptables doesn't exist)?
    And: what is wrong with my Network Mask?

    You need to run these commands. Then you need to fix your errors in the web gui firewall section because on reboot the rules will come up again.


    Code
    iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
