Two vDOM's, one WAN source...

[DaveLeav]

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.

Hi Dave,

Yes you may do so, you have to set at least 3 VDOMs: one root, VDOM1 and VDOM2 and then you have to configure interVDOM links.

In this scenario, Internet traffic should be routed through root VDOM, which is connected to the others via interVDOM links and only root VDOM is physically connected to the Internet. In this topology, the peer VDOMs (1 and 2) are only linked  with the root VDOM, not with each other.

Please review the following link, which shows a full example of the configuration you're asking for.
