Monitoring the Internet Connections of WAN Links with Only Routing Configuration , Ekarin Suethanuwong (Prince of Songkla University, Thailand). Nowadays, an approach using the Netwatch tool to monitor the Internet connections of WAN links has been very popular in Thailand. This approach has been used to solve a failover problem that does not switch over to other Internet-accessible WAN link when one WAN link’s state from a MikroTik router to the connected Internet Service Provider (ISP) is not down but the Internet cannot be accessible due to any possible problem behind the ISP. By means of the approach, the Netwatch tool is used to periodically check a remote host in the Internet using PING packets as well as scripting in both the up and down states of the WAN link is needed to disable and enable the default route of the WAN link. However, this presentation describes an alternative approach to provide the same result without using the Netwatch tool and knowing the scripting at all. Thanks to the website “wiki.mikrotik.com” that provide useful information about this approach. This approach can be simply done by configuring only routes in the route table (i.e. the Route List window in the WinBox program). This approach is presented in both scenarios: (1) one remote host per WAN link and (2) more than one remote host per WAN link. Moreover this presentation demonstrates the use of this approach in the MikroTik router devices as well.
