What happened?

Hello,
We have two pve(proxmox servers) and created two containers(lxc) on each.
We use masquerading between them.
From them to all other machines there is a ping, from the other machines to them there is a ping again, but there isn't ping between the LXC containers .. no matter if the masquerading is with one network or with different ones.

Version

v0.22.0

What OS are you using?

Linux

Relevant log output

There isn't log in journalctl

Seems like a issue similar to #2804

It's not the same, because they aren't behind one firewall router or nat. Every server has NAT individually.
ContainerX on ServerA can't ping ContainerY on ServerB

@josifpeev , I may not be able to simulate the same structure in your network. In my test, I created 3 containers in different VPCs, 1st in DO VPC, 2nd in AWS VPC1, 3rd in AWS VPC2. All join the same Netmaker network. They are able to communicate each other.
The test done in v0.24.1, and ICMP and UDP 52821-51830 all opened to others.
Is there any other settings in your test?
