Custom firewall rules
If you determine that specific traffic is dropped by the SMC because an
appropriate firewall rule does not exist, you can add a custom inbound rule to
allow this traffic through. The rule should map the source and destination
networks for the traffic, the protocol (either TCP, UDP, SVP, or ICMP), and
the port (if not ICMP or SVP).
