I was changing the Network configuration settings in an attempt to add Masquerading to create new VMs that didn't need their own dedicated IPs, but now I lost connectivity to all my VMs, including the ones with their own Failover IPs that were previously working. Can anyone please help me fix my networking configuration?

Hi,
is the issue just the VMs or does the Proxmox host also have internet connection problems?

vmbr0 is working on the Proxmox host shell, but none of the VMs have internet access or are able to access the Internet or any of the OVH gateways.

root@xxxxxxxxx:~# curl --interface vmbr0 "https://google.com"

Hi,
this curl output looks to me like you have an internet connection because I get the same:

Code: 
$ curl "https://google.com"
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="https://www.google.com/">here</A>.
</BODY></HTML>

Apologies for the confusion, that's the output from the Proxmox host shell, NOT the Guest VMs, which do not have any internet connectivity (ex. cannot ping 8.8.8.8) and are unable to even reach the internal OVH network gateways
