I have 2 internet connections connected to a Fortigate 50B. I created a virtual ip on wan1 for port 25 to the server, so that the server can receive mails.
But when wan1 dies, it's switches to the other provider on wan2. So i want to create a virtual ip for port 25 on the other wan (wan2). But when i try to do that I get an error "A duplicate entry already exists."
What am i doing wrong?
