Protecting Data Across a NAT or Firewall
Protecting Data 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.
