Reliable Internet access is a crucial aspect of productivity in any size business or organization. Whether it is the ISP itself having technical difficulties or the Internet modem going bad, some things cannot be quickly repaired and significant downtime can have a substantial negative impact. Having a secondary ISP is generally the method to ensure that Internet access can be made available quickly should the primary ISP go out of service. This is about WebMux multiple gateway network failover solution.
It is important to note that the ISPs should be from different providers. If one provider goes out of service, it is unlikely that the other provider would go out of service at the same time.
Since the two ISPs are from different providers, you will have two different gateways to use. Generally, you would only need to use one at a time and you will only need to switch to the other gateway in the event of the primary ISP going out of service. However, switching to your secondary ISP gateway would require you to manually update all your devices within your private network to use the new gateway. This can be an incredibly cumbersome task if your organization has numerous devices. Having the ability to switch to a different ISP gateway quickly can be a lifesaver, but having to manually reconfigure numerous devices can still be a nightmare.
This is where the WebMux Multiple Gateway feature will come in handy. In this scenario, the WebMux will act as the default gateway for your devices and the WebMux will direct the outbound traffic to the appropriate Internet gateway. The WebMux health check function monitors the Internet gateways to make sure they are available. Should one go down, the WebMux will take that gateway path out of service and direct traffic to the working one.
The most basic setup is to have a gateway farm with one gateway active and the other gateway on standby. The standby gateway will only be used as a last resort. It is also possible to configure the gateway farm to have two or more active gateways. In that case, outbound traffic will be distributed between the two gateways.
