Establishing a

Connection Across a

NAT or Firewall

If your source and target are on opposite sides of a NAT or firewall, you will need special
configurations to accommodate the complex network environment. Additionally, you must have the

hardware already in place and know how to configure the hardware ports. If you do not, see the

reference manual for your hardware.
In this environment, you must have static mapping where a single, internal IP address is always

mapped in a one-to-one coorelation to a single, external IP address. Storage Mirroring cannot handle

dynamic mappings where a single, internal IP address can be mapped to any one of a group of

external IP addresses managed by the router.

Verifying the Storage Mirroring port settings

Storage Mirroring uses specific ports for communication between the Storage Mirroring servers and

Storage Mirroring clients. In order to use Storage Mirroring through a NAT or firewall, you must first

verify the current Storage Mirroring port settings so that you can open the correct ports on your

hardware to allow Storage Mirroring machines to communicate with each other.
Using the following table, locate and record your port settings for each of the Storage Mirroring ports.

The port setting can be found in the following locations.

Management Console—From the Management Console, select File, Options, and go to the

Configuration tab.

Failover Control Center—From the Failover Control Center, select Settings,

Communications.

Storage Mirroring

server—From the Management Console, right-click on a server in the tree in
