accidentally reset the linux firewall.

I've accidentally reset the linux firewall.

Hello, I've accidentally reset the linux firewall. webmin-network-linux firewall clicked the button at the bottom on the page. and all the settings on the page has all been deleted. i was thinking it would go back to the install default settings and not a empty firewall... is there a way to get it back to the installation default settings if so how ?

do i just need to select Reset Firewall then Block all except ports used for virtual hosting, on interface: ?
