Appendix A Troubleshooting A This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the ADE-4300/ADW-4300 and some possible solutions to them. If you follow the suggested steps and the ADE-4300/ADW-4300 still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the ADE-4300/ADW-4300 to configure it.
ADE-4300/ADW-4300 User Guide Problem 2: Some applications do not run properly when using the ADE4300/ADW-4300. Solution 2: The ADE-4300/ADW-4300 processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic. You can also use the DMZ function. This should work with almost every application, but: · It is a security risk, since the firewall is disabled.
Appendix A - Troubleshooting wireless stations. This will mean high access speed is only possible when close to the ADW-4300.
Appendix B About Wireless LANs(ADW-4300 only) B This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: · Ad-hoc · Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.
Appendix B - About Wireless LANs Channels The Wireless Channel sets the radio frequency used for communication. · Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
ADE-4300/ADW-4300 User Guide Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to.
Appendix C About VPNs C Overview A VPN (Virtual Private Network) provides a secure connection between 2 points, over an insecure network - typically the Internet. This secure connection is called a VPN Tunnel. There are many standards and protocols for VPNs. The standard implemented in the ADE-4300/ADW-4300 is IPSec. IPSec IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks.
ADE-4300/ADW-4300 User Guide Because the IKE and IPsec connections are separate, they have different SAs (security associations). Policies VPN configuration settings are stored in Policies. Note that different vendors use different terms. Generally, the terms "VPN Policy", "IPSec Policy", and "IPSec Proposal" have the same meaning. However, some vendors separate IKE Policies (Phase 1 parameters) from IPSec Policies (Phase 2 parameters).
Appendix C - VPNs Common VPN Situations VPN Pass-through Figure 78: VPN Pass-through Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connection. · The PC software can use any VPN protocol supported by the remote VPN. · The remote VPN Server must support client PCs which are behind a NAT router, and so have an IP address which is not valid on the Internet.
ADE-4300/ADW-4300 User Guide Connecting 2 LANs via VPN Figure 80: Connecting 2 VPN Gateways This allows two (2) LANs to be connected. PCs on each endpoint gain secure access to the remote LAN. · The 2 LANs MUST use different IP address ranges. · The VPN Policies at each end determine when a VPN tunnel will be established, and what systems on the remote LAN can be accessed once the VPN connection is established. · It is possible to have simultaneous VPN connections to many remote sites.
