Note - This solution also applies to these appliance models: 1550, 1590, 1600 and 1800.
The tables below list all active Security Management Portal (SMP) ports.
These ports should be opened on any firewall that is protecting the SMP server, either a physical firewall or the Windows Firewall running on the server.
In addition, if the SMP server is hidden behind NAT, then port forwarding must be defined for these ports.
If the managed appliance is behind a firewall, then the same ports must be opened in the reverse direction.
Incoming Ports (from Gateway to the SMP)
Outgoing Ports (from the SMP to the Gateway)
Ports between multiple SMP servers (primary, secondary and JMLS servers)
