How to allow ICMP traffic to pass with Transport firewall rule

You need to add the following rule to the TransPort's standard firewall set to allow ICMP traffic to pass:

Allow outbound FTP traffic
pass out break end proto ftp from any to any port=ftpcnt flags S!A inspect-state
#Allow any other outbound traffic and the replies back in
pass out break end inspect-state
#Allow incoming IPSEC
pass break end proto 50
pass in break end proto udp from any to any port=ike
pass in break end proto udp from any to any port=4500
#Allow any traffic within an IPSEC tunnel in both directions
pass break end oneroute any
#Allow incoming SSH and SFTP
pass in break end proto tcp from any to any port=22 flags S!A inspect-state
#Allow ICMP
pass in break end proto icmp inspect-state
#Allow incoming HTTPS
pass in break end proto tcp from any to any port=443 flags S!A inspect-state
#Block and log everything else including incoming telnet, http and FTP
block log break end
