In order to have two separate views (one for the cockpit and one for the external view) I would like to purchase a second license of X-Plane 12 and run the two instances on one pc and two monitors.
Could someone tell me if is it possible and how to set up the network? Ferdi

not the same PC, need two seperate pcs.

After that there are instructions for external visuals in the manual, but check it works to your pleasing using the demo first.

I like to point you this resource which you might find it handy since you are interested in network and anything you might engage in Xplane.

The X Plane handbook is a excellent resource of information for anyone who is new x plane and want to advance themselves to get the most out of it. Even if you are not new to X Plane is great reference tool and there is always something you can learn.

It covers networking as well as best practice with deplays. Part one covers types of hardware to OS and  performance settings. Part two concentrates on scenery. It $15.00 but i think its worth if you really want to get up and running where you you tried and true methods.

Thanks but I already have that book: it's very useful but unfortunately it doesn't describe my case. I once found instructions somewhere on how to do this type of setting but I lost them. The X-Plane developers themselves advised against this setting due to performance problems but they only reiterated that, in the end, the important thing was to have two licenses and then it didn't matter it they were used on 2 computer or only one.

You say you've done this before or knew how it could be done? 

Aside from configuring a virtual machine with pcie passthrough on a second GPU, I'm not aware of how you could do this. Would have to fake out XP into thinking each is the only instance running and give independent IP addresses.

Looks like linux land could possibly do it.

Create a virtual NIC

Bind a specific process to a NIC

I imagine something might be possible in win given there's a network 'route' command in cmd that acts much like ip in the above examples.

Have not tried to start multiple instances of XP on the same OS at the same time. You'd want to point each to different prf files....unless you had a beefy system that could handle 2 full-fat instances of XP running simultaneously, at least at startup.

I image some off the shelf solution use something VMware might get you there as well.

I finally found the following two posts from X-Plane.org: https://forums.x-plane.org/index.php?/files/file/34630-running-multiple-x-plane-10-copies-on-a-single-computer/&tab=comments#comment-258263 and https://forums.x-plane.org/index.php?/forums/topic/157591-success-running-two-instances-of-xp11-on-one-machine/&. In the past I had tried with X-Plane 11 and it actually worked and with very little frame drop (most of the render options aren't actually needed for the cockpit view so for it just set the render settings to minimum). I will try again. However, it is not very clear whether two licenses are actually necessary; I am not sure but I seem to remember that Laminar Research had disabled the license of a user reiterating that for two instances of X-Plane (even on the same computer) two licenses were still required.
