Well, this is to simulate like if I was behind an external router. (like if you 
are hosted on provider like ovh)
A route should be setup somewhere to say how to reach the network behind 
proxmox host.

This kind of config (replace private by public adress to simulate internet 
network)





[client 10.0.1.1]---->[10.0.1.1---hardware router----10.0.0.1]---->[10.0.0.2 
proxmox host]---------->192.168.0.1 guest
                                                                                
           ---------->192.168.0.2 guest

hardware router : route add 192.168.0.0/24 gw 10.0.0.2
                  default gw: upstream internet bgp router


when your are hosted, you have a small public range (192.168.0.0./29), and this 
range is setup with a route in hosting provider hardware router
to go through proxmox ip.


In your setup, you need proxy-arp on host interface because you don't have the 
route on the client or between the client and the target network, so you need 
arpproxy on host to trick.
But for me, this kind of setup is not real "routing", It's more like a 
pseudo-bridge with arp tricks.

You setup a route for the second network? Why don’t you simply use the same 
network for testing?
