My scenario is very simple
I have two internet connections:
1- Primary connection dedicated for Exchange server that is published to the internet (Ports published: TCP/443; TCP/25 only)
2- Secondary connection dedicated for local users and it's main purpose to allow the users surf the internet and as a backup access to the exchange server if the primary connection goes down.
All PC's and Servers are on the same LAN (22.214.171.124/24)
My questions are:
1- how to configure a policy routing to always allow exchange server pass through primary connection (src-nat or masquerade) and to serve any external request to the exchange that is published (dst-nat)?
2- how to configure a policy routing to always allow traffic from users to pass through the secondary connection? and how can I make sure that if I request exchange server (OWA service on port TCP/443) on secondary connection will route to the published service (HTTPS OWA)?
BTW, I have read the following tutorial http://blog.butchevans.com/2008/09/mikr ... n-example/ but unfortunately no luck, no support and no dice!
