Using Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when Prestige
cannot connect to the Internet through it's normal gateway. Thus make your
backup gateway as an auxiliary backup of your WAN connection. Once
Prestige detects it's WAN connectivity is broken, Prestige will try to forward
outgoing traffic to backup gateway that users specify in traffic redirect
configuration menu.
You can deploy the backup gateway on the WAN or LAN of Prestige. However, if you would like to deploy the backup gateway on the WAN of Prestige, please make sure that your Prestige has a static WAN IP address at first. Otherwise, we recommend you to deploy the backup gateway on the LAN of Prestige.
Traffic Redirect on WAN port
When Prestige has a dynamic IP address on it's WAN port, it may be easier to connect backup gateway to the LAN of Prestige.
Traffic Redirect on LAN port
Configure parameters that determine when Prestige will forward WAN traffic to the backup gateway using SMT Menu 11.6-Traffic Redirect Setup.
Menu 11.1 - Remote Node Profile |
Menu 11.6 - Traffic Redirect Setup Active= Yes Configuration: Backup Gateway IP Address= 192.168.1.50 Metric= 15 Check WAN IP Address= 202.132.154.1 Fail Tolerance= 5 Period(sec)= 30 Timeout(sec)= 2 Press ENTER to Confirm or ESC to Cancel: |
Key Settings:
Active | Press [Space BAR] and select Yes (to enable) or No (to disable) traffic redirect setup. |
Backup Gateway IP Address | The IP address of your backup gateway. Prestige automatically forwards outgoing traffic to this IP address if Prestige's Internet connection terminates. |
Metric | Enter a number from 1 to 15 to give your traffic redirect route a priority number. The smaller the number, the higher priority the route has. |
Check WAN IP Address | Configure a reliable server on Internet (for example, your ISP's DNS server address) for Prestige to check it's WAN connectivity periodically. If you leave this field as 0.0.0.0, Prestige will check it's default gateway IP address instead. |
Fail Tolerance | Specify the number of times your Prestige may attempt and fail to connect to Internet before triggering traffic redirect connection. |
Period | Specify the period that Prestige would check it's WAN connectivity. |
Timeout | Specify the seconds that Prestige would wait for a response from the reliable server. |
You can also configure traffic redirect via web configuration. The configuration page is in ADVANCED/WAN/Traffic Redirect.
In case your are using Presitge with firewall function turns on, it's strongly recommended that you deploy the backup gateway in IP alias segment. You can refer to here for how to use IP alias in Prestige, and firewall FAQ for the reason why we make such suggestion.
