Configuring the ANG-1100 with Aurorean Web Config

Release and click OK. Then click Renew All and click OK.

-For Windows NT/2000 systems, type ipconfig /release and press ENTER. Then type ipconfig /renew and press ENTER.

-For Macintosh systems, check the TCP-IP control panel.

3If you chose the DHCP option or changed the DNS or WINS default entries, a window appears detailing the reconfiguration changes and prompting you to reboot the ANG-1100. Click Reboot Now.

NOTE

If you press the Reset button after configuring your ANG-1100, you will lose your entire configuration. Any settings you supplied must then be re-entered. We strongly recommend that you do not use the Reset button unless you want the configuration to return to factory defaults.

Setting Up the Firewall

Firewall security is established in a one-way, outbound configuration by default on the ANG-1100’s External interface. A strong combination of firewall and NAT security is achieved to allow users out from their ANGs but disallow any others in from the Internet. The firewall also provides the following optional choices to control management of the ANG-1100 via HTTP and/or Telnet:

!Enable/disable HTTP/Telnet from the Trusted network

!Enable/disable HTTP/Telnet over the VPN tunnels

!Enable/disable HTTP/Telnet in the clear from the Internet

Enabling any of these options allows ANG-1100 management via the Web or Telnet. We recommend that you accept the factory default settings which allow Web and Telnet management access on the Trusted LAN connection but disable these permissions on the Internet and VPN Gateway connections.

WARNING

DO NOT LEAVE ALL THREE CONNECTIONS DISABLED. If you do so, you will be UNABLE TO CONFIGURE THE ANG-1100 without resetting the system and returning to the factory default configuration.
