Flow Preference to a non-internet WAN port

[Warpedisc]

Hi

Is it possible to use Flow Preference out a WAN interface that does not touch the internet? Basically I am attempting to NAT traffic destined for a specific IP and Port out the WAN 2 interface on a MX68. The WAN 2 interface will connect to an internal network where a server lives but internet access out this interface will be unavailable.

I can explain further if needed. Any help will be much appreciated!!

WAN ports must be connected to Internet. They will not forward traffic if they do not have a path to the Internet.

@jdsilva is right.  Without a path to the Internet the WAN port will be considered to have failed, and the path made unavailable.

Have you considered created a extra VLAN interface and routing via that?

Are you suggesting to setup a VLAN on one of the MX68 LAN interfaces? I need to be able NAT the traffic because its touching another organizations network. Since they may be using the same private subnets I am or have summarized routes I need to make sure I don't interfere with them. I am open to your suggestions though, I run into this type of situation pretty regularly.
