Firewalls

LiveVault Online Backup Service Agents use a fixed TCP port to communicate with the LiveVault Internet Gateway (LVIG). When you install the Agent software, a port selection utility determines which TCP port to use and configures the port.

If your Agent is not able to connect with either of its LVIGs, your firewall may be the source of the problem. If your firewall is the problem, then you must modify your firewall to allow the Agent to establish a session with its LVIG.

For more information about firewall configuration for LiveVault Online Backup Service, see Firewall Configuration for Use with Agents.

Proxy servers

LiveVault Online Backup Service can be set up in a Microsoft Proxy Server 2.0/ISA 2000 environment where:

The LiveVault Online Backup Service Agent machine is always "inside" the Proxy Server.
The LiveVault Online Backup Service Agent machine is a Winsock Proxy Client.

For more information about using MS Proxy Server 2.0/ISA 2000 with LiveVault Online Backup Service, see Microsoft Proxy Server 2.0 or Internet Security and Acceleration (ISA) Server 2000.

If your Agent computers are behind both an MS Proxy Server and a firewall, contact Customer Service for assistance.

If you are using a different vendor's proxy server, contact Customer Service for assistance. We have not tested with other vendors' proxy servers; however, LiveVault Online Backup Service has been set up to work with some other proxy servers that provide a client-side component with a Winsock proxy filter.

Proxy firewalls

Agent computers and LVIGs cannot communicate through a Proxy firewall. However many Proxy firewalls can be modified to allow access. If you are using a Proxy firewall, contact Customer Service for assistance.
