Configuring Your Firewalls

We have a number of public IP addresses which need to be added to firewall configurations. Without this, third party systems may have difficulty in establishing a connection to and from us.

  • 203.223.63.140 - this is our virtual IP address, which is where we accept incoming connections. All outgoing connections should also originate from this address.
  • 203.223.63.141, 203.223.63.142, 203.223.63.145 - this is are our primary load balancers. In the event of an emergency, we may fail over to any of the IP addresses listed here. If that were to happen, connections from our system may appear come from either

These public addresses apply to both our test and production environments.
