I have a Fortinet running in a DC, I am looking at setting up vDOM's (I should have done at the start I know), I have a single internet presentation with 6 IP's into our untrust switch. Can I setup two vDOM's that share the same WAN link? The presentation would be two separate lines from the untrust switch but the WAN gateway would the same in each vDOM. I don't want to use a gateway router as I have seen in one of the cookbooks.
This setup is close but specifies two separate ISP's - http://cookbook.fortinet.com/vdom-configuration-54/
