Network Requirements

  • Firewalls
    OPM
     sends and receives emails using the standard SMTP port (25). This port should be opened on all firewalls (including 
    Windows
     Firewall) that protect the 
    OPM
     application servers.
    Simply turning 
    Windows
     Firewall off might not guarantee the port is opened. Turn on 
    Windows
     Firewall and create inbound and outbound to allow TCP traffic on port 25.
  • Anti virus software
    Anti virus software installed on 
    OPM
     application servers might affect 
    OPM
     operations if configured incorrectly. You should uninstall anti virus software if its behavior is uncertain.
  • Server Clock Synchronization
    All application and database server clocks must be synchronized with the network server time.
