For the createFirewallRule and createEgressFirewallRule APIs the port parameters are optional. If you don't specify the port range for the prototocol (TCP) it allows all the tcp traffic.
Ingress: 1. First firewall rules filters traffic then PF/Static NAT will NAT to the specific VM. If you specify tcp with out ports all tcp traffic on IP is allowed then PF/Static NAT rule (PF ports) decides to which VM the traffic should be NATed. Egress: Traffic from guest network to public network is filtered by egress. If you specify the tcp with out ports all egress tcp traffic is allowed.
