This line opens virtual port 443 for TCP on the first added physical external Ethernet port,
External1, on all nodes in the HP XC system.
The text -i External1 matches all nodes, so virtual port 443 will be open on all nodes
with External1 connections.

This line opens the ftp virtual ports (20 and 21) on the first added physical external Ethernet
port, External1, on node n19.
Additional examples of this syntax are as follows:
-A RH-Firewall-1-INPUT -i n23::External1 -p tcp -m tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -i n[5,17]::External1 -p tcp -m tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -i n[9-11,20,33-34]::External1 -p tcp -m tcp --dport 22 -j ACCEPT
