List iptables with line numbers:
iptables -L --line-numbers
Insert a policy just before the REJECT all policy in the VPM-Firewall-INPUT chain. In this example, the REJECT all policy has line number 7:
iptables -I VPM-Firewall-INPUT 7 -p udp --dport 5620 -j ACCEPT
Save the new policy:
service iptables save
