Make a permanent rule? kvm

[ricrey]

Hello, I have some virtualized dedicated servers with "Virtualizor with KVM", I have CSF installed and everything works fine... but every time I make a change and I have to restart the LFD and CSF the internet of the VPS KVM is blocked... I have to place the command:

Code: Select all

/sbin/iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT

I would like to know if there is a way to make this command permanent even if changes are made to the firewall, I hope you can help me, thanks.
