Appendix C: Troubleshooting
Overview
This chapter covers some common problems that may be encountered while using the Twin WAN Gateway and some possible solutions to them. If you follow the suggested steps and the Twin WAN Gateway still does not function properly, contact XiNCOM for further advice.
Problem: |
I can't connect to the Twin WAN Gateway to configure it. |
Solution: |
Check the following:
- The Twin WAN Gateway is properly installed, LAN connections are OK, and the device is powered ON.
- Ensure that your PC and the Twin WAN Gateway are on the same network segment.
- If your PC is set to Obtain an IP Address automatically (DHCP client), restart it.
- If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.1.2 to 192.168.1.254 and thus compatible with the Twin WAN Gateway’s default IP Address of 192.168.1.1.
- Also, the Network Mask should be set to 255.255.255.0 to match the Twin WAN Gateway.
- In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.
|
Ensure your TCP/IP settings are correct, as follows:
Problem 1: |
When I enter a URL or IP address I get a time out error. |
Solution 1: |
A number of things could be causing this. Try the following troubleshooting steps:
- Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.
- If the PCs are configured correctly, but still not working, check the Twin WAN Gateway. Ensure that it is connected and ON. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)
- If the Twin WAN Gateway is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly.
|
| Problem 1: |
Some applications do not run properly when using the Twin WAN Gateway. |
| Solution 1: |
The Twin WAN Gateway processes the data that passes through it and therefore it does not act as a transparent device.
- Use the Special Applications feature to allow Internet applications to function correctly through the Twin WAN Gateway.
- If this does not solve the problem, use the DMZ function. This solution should work with most applications but there is a security risk to the DMZ PC- the Twin WAN Gateway's firewall is disabled for any PC setup through DMZ. Only one (1) PC can use this feature.
