IP Filter Settings - Up to 32 rules may be made to limit the type of packets allowed to pass between the WAN and LAN. Each rule may specify that packets meeting specifi c criteria (source or destination IP Address, Protocol, etc.) from either the WAN or the LAN are ignored, rejected, or accepted. You may choose that packets from the:• WAN side (packets coming from the WAN side will be fi ltered) • LAN side (packets from the LAN side will be fi ltered)are:• Ignored (stops the packet and does not route it)Basic Filter SettingFTP and WEB. * If IDENT requests are for-warded to a LAN side client by address translation setting (DMZ or TCP port :113 ), this basic rule is ignored.

You may also choose:• Destination IP Address - The IP address to be fi ltered.• Source IP Address - The IP address designated for fi ltering. If all IP addresses must be fi ltered, leave this box blank. Warning: If administrator makes a rule that all packets from LAN are Ignored or Rejected, they will no longer have access to the AirStation confi guration screens. This rule prohibits further setup from a wireless or wired computer. The AirStation can be returned to the factory default settings by holding down the INIT button on the back of the unit for fi ve seconds or until the red DIAG light becomes solid.

79Troubleshooting WDS (Step-by-Step Instructions)The most common issue with WDS installations is using the wrong MAC address. The proper MAC Ad-dress for the access points is the ‘Wireless MAC Address’. The best place to document this is under the ‘System Information’ section of the configuration web page. For proper setup, please continue reading this document.Problem:Communication problems with WDS (wireless bridging/repeating).Cause:WDS is a very complex bridging system, and is not part of the 802.11b or 802.11g standards.Restrictions:Please verify that the following conditions are met (if just one condition is not satisfied, then WDS can-not be used on the wireless network): 1. All wireless access points in the wireless bridge need to be from the same vendor (e.g. all Buffalo access points). (At time of publication, the Apple Airport Extreme WILL work in WDS with Buffalo G54 access points.) 2. No single access point can communicate with more then six other access points in the wireless bridge. Troubleshooting
80The following is a list of good practices with WDS: 1. Start the wireless bridge system with only two access points and then add more access points. 2. Setup all access points in the wireless bridge in close proximity before they are deployed to their proper location. 3. Only one access point in the wireless bridge should be serving DHCP and routing services unless a routed wired network exists. Proper Setup:Please follow the following steps to properly setup WDS. 1. It is recommended that all access points in the bridge are reset to their factory default settings. This is done by holding the INIT button on the rear of the access point down for 5-10 seconds. 2. Login to the first access point in the wireless bridge (this should be the DHCP server enabled ac-cess point if there is not already a routed wired network). 3. Click on the ‘Advanced’ button. 4. The wireless settings page will appear. Select the proper settings for the wireless network. Record all settings on a piece of paper. All settings except for the SSID need to be identical amongst all access points in the bridge. If roaming is desired, then make sure the SSID settings are identical as well. Press the ‘Apply’ button after any changes are made. If the IP address was changed, then reconnecting to the access point for configuration will require accessing it via its new IP address in a web browser (e.g. http://NEW_IP_ADDRESS).5. Click on the ‘LAN port’ link on the left. Troubleshooting
816. Check that the ‘LAN side IP address’ values are correct for your network, or leave them as default. Record the ‘LAN side IP address’. Press the ‘Apply’ button if any settings on this page have been changed.7. Click on the ‘Management’ link on the left.8. The System Information page will appear. In the Wireless section of the table record the MAC address, including the colons (i.e. “00:00:0A:1B:2C:DF”). Please make sure the MAC address is recorded from the Wireless section and not the other sections.9. Logout of the access point by clicking on the ‘Logout’ link on the left. Close the browser window.10. Login to the second access point in the wireless bridge.11. Click on the ‘Advanced’ button. 12. The wireless settings page will appear. Select the proper settings for the wireless network. Refer to the settings recorded from the first access point. All settings except for the SSID need to be identical for all access points in the bridge. If roaming is desired, then make sure the SSID settings are identi-cal as well.13. Click on the ‘LAN port’ link on the left. 14. Make sure that the ‘IP address’ for the ‘LAN side IP address’ setting is different from that of the first access point. The IP addresses cannot be the same, but they should be on the same network. It is recommended that the IP address of the second access point is one higher then that of the first ac-cess point. Thus, if access point one’s address is 1.1.1.1, then access point two’s address should be 1.1.1.2. If there is a ‘DHCP server function’ setting on this page, then make sure to set it to ‘Disabled’. Press the ‘Apply’ button when finished. Troubleshooting
8215. Click on the ‘Wireless bridge (WDS)’ link on the left. 16. Enable the WDS function and press the ‘Set’ button. 17. Enter the Wireless MAC Address of the first access point (which was recorded on Step 8) into the field that say ‘MAC Address of AirStation(Wireless)’ (include the :’s). Press the ‘Add’ button. 18. The Wireless MAC address inputted on the step above will appear in the ‘Connected AirStation’ table. Please check that the checkbox under enable is checked, and then press the ‘Enable marked item’ button.19. At the top of the page, press the ‘Apply’ button.20. Once the router has rebooted, click on the ‘Management’ tab on the left.21. The System Information page will appear. In the Wireless section of the table record the MAC ad-dress (including the :’s). Please make sure the MAC address is recorded from the Wireless section and not the other sections.22. Logout of the access point by clicking on the ‘Logout’ link on the left. Close the browser window.23. Login to access point one again.24. Click on the ‘Advanced’ button.25. Click on the ‘Wireless bridge (WDS)’ link on the left.26. Enable the WDS function and press the ‘Apply’ button.27. Enter the Wireless MAC Address of the first access point (which was recorded on Step 21) into the field that say ‘MAC Address of AirStation(Wireless)’ (include the :’s). Press the ‘Add’ button.Troubleshooting
8329. At the top of the page, press the ‘Apply’ button.30. Once the router has rebooted, click on the ‘Management’ tab on the left.31. Click on the ‘PING test’ link on the left.32. In the ‘Destination’ field enter the IP address of the second access point and press the ‘OK’ button. a. If the ‘Result’ section of the table reports information like, “1st: 64 bytes from IP_ADDRESS” then the WDS bridge is effectively working. b. If the ‘Result’ section of the table reports “Destination Host Unreachable”, then an error has oc-curred during the setup. WDS is a complicated bridging system with a lot of variables. If there are still problems with WDS con-figuration on the network, then please call our 24/7 technical support line at 1-866-752-6210. Troubleshooting
