Using firewalls
If your servers are on opposite sides of a NAT or firewall, you will need to configure your
hardware to accommodate Storage Mirroring Data Migrationcommunications. 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 a NAT or firewall environment, you must have a static mapping where a single,
internal IP address is always mapped in a one-to-one correlation to a single, external IP
address. Storage Mirroring Data Migration 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.
Storage Mirroring Data Migration ports
Storage Mirroring Data Migration port information is stored in configuration files. By
default, ports 6320, 6330, and 6340 are used. If you have to modify which ports are used,
you will have to modify two configuration files. Be careful when modifying these
configuration files. If you modify them incorrectly, Storage Mirroring Data Migration may
no longer work correctly.
1. Open the file JobMgr.dll.config in your Storage Mirroring Data Migration installation
directory. By default, this is \Program Files\StorageWorks\Storage Mirroring. You
may need to associate the .config file extension with Notepad or another text
editor.
2. Locate the following lines near the top of the configuration file.
<add key="IdentificationPort" value="6320"/>
<add key="LivewirePort" value ="6340"/>
<add key="VRAPort" value="6330"/>
3. Change the port numbers as necessary. Do not change any other information.
4. Save the configuration file.
5. Repeat steps 1 through 4 with the file Livewire.exe.config, using the same port
numbers for each key as you used in the JobMgr.dll.config file. The ports must
match between all Storage Mirroring Data Migration servers and clients.
6. If you changed the IdentificationPort in the configuration files, you must also
change a port in Storage Mirroring because Storage Mirroring Data Migration also
relies on that port setting.
