Configuring the ANG-1100 with Aurorean Web Config
Release and click OK. Then click Renew All and click OK.

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.
