Hi, We are configuring firewall for a couple VM's. After enabling the firewall for each VM, it must be rebooted (cold) . We want now to enable the firewall option in hardware>network device for all VM's. And then disable the firewall in Firewall>options enable flag by default. 1. The question now is what does this enable flag in Firewall>options do exactly? 2. Will this solution have a negative impact on our nf_conntrack table. Will all the VM's effect the nf_conntrack table? Or will the nf_conntrack table be effected only by the vm's by which the enable flag in Firewall>options is turned on.
