Hi,
The hosts are in an OVH data center, but I do not think this has anything to do with their hardware.
I am using proxmox to host some VMs. I have two nodes clustered together using tinc as a VPN. This all seems to be working great. The problem I am having is using a PRIVATE IP address on a VM and getting that VM to have an internet connection (not port forwarding to the VM, a internet connection to download packages etc).
I can set up a VM using the failover technique mentioned in the OVH bridge guide, that is working. What I want is a private IP (192.168.15.10) to have internet accesss (e.g able to ping google.com).
On node1 (where the VM is) I have the following interface settings:
(NOTE: eddited out IPV6 stuff)
On the VM I give it a NIC on vmbr1 and assign the IP (example 192.168.15.10). I can ping both Proxmox hosts, but cannot access the internet. I cannot work out why this is not working and need some help debugging.
Thanks!
