It is not about limit but more about use case. Could you explain your use
case why using localnet ports here while the VMs can be connected through
logical router on overlay? Did my patch work for you? Does it work also
when you remove the localnet ports?

Mickey mentioned scenarios when a combination of localnet ports and logical
router is valid, which are for gateway use cases, and it seems to me that
is not your case cause you are just try to connect two VMs.

> Here you have both logical router and localnet ports, which doesn't seems
