So i could try to set all of them to a manually set port, or i cannot use auto generated VLANs because some MX are in the template, while others are not...
I forget that manually NAT Traversal needs an IP Adress AND port specified.
How it is supposed to work in a template? Obviously you can't have multiple different networks with same public IP and port. It would make more sense to only specify the port while using the dhcp given public ip.
