Internet access for Proxmox VXLAN (lemmy.zip)

What is the best way to provide internet access to guests on a Proxmox VXLAN? Is it:

One node (host) in the cluster is the default gateway, all traffic is routed through it. Sounds clean and simple but there's multiple layers of jank to get it working, if it works at all
Have a guest (lxc or VM) on the VXLAN act as a gateway. Give it two NICs - one on the vnet and another on the hosts bridge (physical lan), route traffic through the second.

My default approach is the first but despite hours of tinkering and forwarding tricks it never works. I'm leaning more to the second but having a dedicated gateway guest seems like a waste of resources - logically the host should be doing it.

And yes, SNAT is enabled 😅

Do you need VXlan? Unless you are doing something really funky, regular vlans should work fine. VXlan is only really useful in very large environments where you want to have layer 2 traffic flow over layer 3 networks. I would strongly recommend that you just stick to regular vlans since they are simple to work with and all you need is a router somewhere on your network to terminate the connection.
