Use GRE-tunneled IPs for Proxmox, possible?
I am experimenting with GRE-tunneled IP(v4)s on hypervisors, potentially providing additional IPs to host a few connectable virtual servers on new Kimsufis.
A hypervisor node is running KVM with Proxmox VE. Currently a GRE tunnel between a distant server and the hypervisor node is up and functional, but I can't find a way to bridge the tunneled IP to a KVM VPS's interface due to limited experience.
I wonder if this is at all possible and if possible, how to configure the bridge (especially on the choice of netmask and gateway).
Also, will running a container instead like OpenVZ make it easier?
