Yes, exactly, in this case, no neep arp in this case.

2 possibility
---------------

1) you setup 255.225.255.255 netmask for guest, and gateway is himself. 

2) you setup the real netmask for guest (/30 for example), 
so in this case the proxmox host should have an ip in the /30  and guest use this ip as gateway.

But in that case it make no sense to setup arp on the external interface, so 
we can simply skip that step?

All hetzner/ovh configuration I saw so far have routing information for those 
addresses, so we can extract network/netmask from there?
