Hi Varun, No there’s no method for this, all firewall rules for the VR are contained in the CloudStack database and written on demand when the VR is created or firewall changes made.

It looks like /etc/iptables/router_rules.v4 on the VR is the file that's being created but I am looking for the script that creates this file. Any insight is appreciated.
