MX Site-to-site cross traffic

[Abedjoud]

Hello, 

I am having quite a peculiar issue that I can't seem to figure how to resolve. I have a setup consisting of 1 MX appliance and I have 2 non-meraki peers I need to connect to. The connections are working perfectly. However, when VPN 1 tries to communicate with a client on VPN 2, cross traffic does not work. I understand that the ideal solution would be to establish an independent tunnel between VPN1 and VPN2. However, we do not control those networks and they are only setup for connecting to our MX. Any communication between VPN1 and VPN2 will need to happen through that MX appliance. When we had a Sonicwall, this was working with no issues. However, we can't seem to get it to work in the MX appliance even though we have setup static routes between the 2 subnets. Any help would be appreciated!

So, if I understand correctly, I cannot setup a manual nat traversal on my Meraki for my non-meraki peers?

Yes, unfortunately that is the case.
