Updating the Firewall Encryption

The SuperStack

3 Firewall is shipped with DES

encryption as standard and can be upgraded to

higher levels of encryption including 3DES. See

“Downloading the Encryption Method” below for

details.

If you are using Virtual Private Networking (VPN) to

connect your sites together then all your Firewalls

must be set to the same level of encryption.

Downloading the Encryption Method

To upgrade you Firewall’s firmware, enter the Web

address http://www.3com.com/ssfirewall

into your Web browser and click on the firmware

you want to download.

Depending on your location and the laws in your

country you may have to provide details about your-

self and your business. If this is the case, the form

shown in Figure 1 displays.
