I have been scratching my head for quite a while on this one ...
We are a wisp, getting our internet connection from 6 DSL lines through 2 cisco boxes (3 lines on each). The cisco boxes feed a linux machine with 3 Nics that redistribute the traffic in our network. Everything works fine, except that the http requests coming from outside are only answered if coming through one of the 2 cisco boxes (let's say R1) .Unless R1 is disconnected from the network, the requests coming from the links attached to R2 are never answered (time out)- Looks like the linux box always tries to send the http traffic back through R1, even though the request comes from the other links -
We have decided to replace the linux box with another cisco router to make it easier ?
Is it possible to configure a route map to redirect the answer through the same interface it came from ?
How do I go about that ?
Where should I configure the route map ? R1 ? R2 ? Or New Cisco box ?
On wich interface should I apply the route map ?
Thanks for your help !
