Dual Wan loadbalance with Xr500 behind, I don't get Nat open.

[Phantomblu]

Hello everyone. I have for some years xr500 and I follow you assiduously in this forum and in the Negear x the beta . I would like to ask for help on the fact that I can not have a totally open NAT . Unfortunately my xr 500 is placed in this way: I have two vdsl lines managed each with AVM Fritzbox 7590 and behind them an Edgerouter x that manages both for the load balance, behind the latter I have xr 500 ... I tried to cascade starting from the first in DMZ , but I never get Nat open...... Having in xr 500 the latest firmware in beta , sometimes for data inconsistency I had to restart it .

I think the biggest problem is Edgerouter x because it doesn't have a simple management for the DMZ and I can't set it in the most appropriate way... I only ask if there is someone who can help me, however I thank you in advance

This is a quite a niche setup so it may be difficult, but just so I'm following, the Edge is in the DMZ of each Fritzbox is that right? Then the Edge doesn't have a DMZ but does it have port forwarding? If so you could forward ALL ports to the XR and that may allow for an Open NAT.

In fact Edge does not have a DMZ, but port forwarding. I will try as you said. Thank you
