[pve-devel] [PATCH 2/2] improve arp setup

[Alexandre DERUMIER]

Well, this is this kind of setup:



client-------->router(10.3.94.1)--------->(10.3.94.31=eth0)proxmox host--------->192.168.1.2(guest)



router config : route add 192.168.1.2 gw 10.3.94.31
                default gw: upstream internet router


proxmox host : route add -net 192.168.1.2 netmask 255.255.255.255 dev tapxxxx 
               default gw 10.3.94.1


guest : default gw 192.168.1.2


so packet is routed through proxmox host.



This is exactly the same setup with ovh or hetzner, guest gateway is the proxmox host(or guest himself with /32mask),
because guest network is != external router.

This is a route to the internal tap device! 

If you do not have an external route, the VM is not accessible from external sites?
