Struggle with Proxmox configuration

Hi,

Incoming flow is working fine.

I can receive incoming email to my Proxmox gateway and relay them successfully to downstream Exchange.

Outgoing flow: emails getting stuck in Proxmox. Getting connection timed-out /network is unreachable errors.

I suspect that the problem is caused by port 25 being used by Proxmox for sending ?!

Perhaps Google SMTP do not accept traffic on 25?!

It must be something dead simple that I am missing

Any help and/or ideas would be really appreciated.

Cheers,

Konrado
