VM's not reachable when in different nodes

[Jlourenco]

Hello,

I have two proxmox servers hosted on hetzner, both in the same cluster and within the same vSwitch.
Using one external IP's for each VM, they can reach the WWW and I can reach them from my home network.
VM's on the same host can reach each other but if I try to ping between two VM's that are on different Hosts it doesn't work.

My current interfaces on both hosts is the following:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp41s0
iface enp41s0 inet static
        address 157.xx.yy.zz/26
        netmask 255.255.255.xxx
        gateway 157.xx.yy.zz
        up route add -net 157.xx.yy.zz netmask 255.255.255.192 gw 157.xx.yy.zz dev enp41s0

iface enp41s0.4000 inet manual
        vlan-raw-device enp41s0
        mtu 1400

auto vmbr4000
iface vmbr4000 inet static
        address 10.10.10.1
        netmask 255.255.255.0
        bridge_ports enp41s0.4000
        bridge_stp off
        bridge_fd 0
        mtu 1400

Anyone has any clue why?

Thanks

After a milion hours reading and testing I found out that I needed to add:
bridge_vlan_aware yes
To the vmbr in order for the public ips to work.

Internal ips are still an issue tho, I was not able to create an internal network cross hosts yet.
If anyone knows how I would be thankful for any info :/

Thanks.
