I have a task where I need to be able to use EZVPN with split tunnel but still have access to an external server from the corporate network as the external server will only accept connections from the corporate public IP address.
So I have not only included the corporate C class in the interesting traffic but also the IP address of the external server.
So all good so far, traffic for the corporate network goes down the tunnel as well as the IP address for the external server.
Now comes the problem, I am trying to send the public IP traffic for the external server out of the corporate network into the public internet but it just drops and does not get back out the same interface into the internet.
I checked out this procedure and it did not help as the route map counters do not increase with my attempt to reach the external router.
Solution using Route Map to set Next Hop to Loopback
And to just test the process, I removed the split tunnel and just have everything going down the tunnel so I can test with any web site. I can access a server on the corporate network but alas it will not allow me to access any site on the network.
Its a cisco 870 router and here is the config
Any help would be much appreciated, and I have put the ip policy statement on both the ATM and Dialer out of desperation but I suspect it should just go on the Dialer.
