oh, you have also an ip on proxmox host in the vm network ? (can you post your host config and guest config example ?).


If yes, why not simple use a bridge and put tap interface on it. no arp proxy should be need, and we should have true routing.(like with libvirt)


client(10.0.0.2/24)----------->[eth0--vmbr0(10.0.0.1/24)proxmox-----vmbr1(192.168.0.1/24)]<-------------vmtap(192.168.0.2/24)



client : defaut gw 10.0.0.1
guest vm : default gw 192.168.0.1

and just enable forwarding on proxmox host.

For example, let us assume your local network 192.168.1.0/24 

So the /etc/network/interfaces on the proxmox node can be: 

auto eth0 
iface eth0 inet statis 
address 192.168.1.2 
netmask 255.255.255.0 
gateway 192.168.1.1 

Note: above is just an example 

Now you can start VMs in routed mode using any address within that network.
