Using firewalls
Storage Mirroring Data Migration can be used over a wide area network (WAN) through
firewalls, but it does not support Network Address Translation (NAT) configurations.
If your servers are on opposite sides of a firewall, you will need to configure your
hardware to accommodate Storage Mirroring Data Migration communications. 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.
Storage Mirroring Data Migration ports
Storage Mirroring Data Migration port information is stored in configuration files. By
default, ports 6320, 6325, 6330, and 6340 are used. If desired, you can modify some of
these ports. However, not all of the ports can be modified.
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\Storage Works\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.
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 DTMove.exe.config, using the same port
numbers for each key as you used in the JobMgr.dll.config file.
6. Repeat steps 1 through 5 for each Storage Mirroring Data Migration server. The
ports must match between all Storage Mirroring Data Migration servers and clients.
7. If you changed the IdentificationPort in the configuration files, you must also
change a port in Storage Mirroring Recover because Storage Mirroring Data
Migration also relies on that port setting.
