Hi All ,
we have a situation where i found the asymmetric routing , we have two connectivity from the client network to the the data center , Primary connectivity is via the wan link and secondary as vpn tunnel over the 4 G which terminate on watchGuard . we are using ospf as a routing protocol .
Here is situation , when we are enabling the tunnel which is same Cisco box , some of the traffic goes the primary wan link and other from the tunnel . we wanted to setup a fail-over scenario where if the wan link goes down the tunnel take the lan traffic , In my case , sometimes the traffic is getting diverse and some time the return traffic is coming from the tunnel route . Please see the diagram as attached , need suggestion as the asymmetric routing impacting the lan traffic , At the moment i have disable the tunnel
