[pve-devel] [PATCH] add routed network mode

Don't understand, guest and host have same gateway ? (where is defined 192.168.1.1 ?)


>>Because requiring an additional bridge generates a lot of unresolved problems (migration?).

I think it resolve migration, if your client is on the same external network  than proxmox host.
If client is behind a front router, I doesn't work because router direct forward to proxmox host with hardcoded route. 


>>And AFAIK it works perfectly for hosters like hetzner/OVH which apply mac restrictions.

Ok, great, I was not sure about this.

host config: 
auto eth0 
iface eth0 inet statis 
address 192.168.1.2 
netmask 255.255.255.0 
gateway 192.168.1.1 

guest config: 
iface eth0 inet statis 
address 192.168.1.3 
netmask 255.255.255.0 
gateway 192.168.1.1

Because requiring an additional bridge generates a lot of unresolved problems (migration?). 
Isn't above setup simpler? - Normally, the user does not need to setup anything. 

And AFAIK it works perfectly for hosters like hetzner/OVH which apply mac restrictions.
