Online Backup configuration with Firewalls

Summary

In order to operate, the online backup software needs to establish a session with the Turbo Backup Data Center on ports 80 and 443. If you have a firewall installed, you need to allow our software to access port 80 and 443.

In a standard firewall configuration there is an inside network interface (i.e. your LAN with the online backup software) and an outside network interface (i.e. the Internet or WAN). The inside network is considered to be 'trusted', while the outside network is 'not trusted'.

Connections with the Data Center are always initiated by the Online Backup software-client. ( Turbo Backup never initiates a connection to the online backup client.) Therefore, you must allow ports 80 and 443 for the TCP protocol for the inside network interface.

If you do not use DHCP for the online backup client computer, you have additional flexibility:

• You can specify in the firewall that only the online backup client computer's IP address can use ports 80 and 443.
• Depending on your firewall's configuration, you may even be able to set up a range of IP addresses.

Setup

Transparency
1. Most default firewall configurations provide transparency for users inside your firewall, but not for the users outside the wall. An online backup client needs transparency for the connection with the Data Center. Therefore, you must either set transparency ON for the internal network interface (if it is not ON yet), or allow the connection on ports 80 and 443 to be transparent. This will depend on the type of firewall you are using.

2. There is no need for transparency on the outside network interface.

Ports
1. The basic configuration required to setup your firewall for online backup client activities (backup/
restore) is to allow ports 80 and 443 for the TCP protocol.

2. If the online backup client computer has more than one network interface (assuming the client
computer is running Windows NT / 2000 / XP / 2003) and has default gateways on each interface, then you must modify the routing table manually to include the network from which the online backup User machine is connecting.

Conclusion

Most home users do not need to make any changes to there firewall or internet connection to allow our software to work. Some business user might need to make some changes to the network firewall.
