Do we really need proxyarp ? I mean, arp request shouldn't go to external vmbr0 unless eth0 is plugged on same bridge than vm nic



>>+my $external_iface = 'vmbr0'; # fixme: autotetect?

I think we can simply detect the vmbrX with the defaut gw ?

So, if I understand you don't use bridge ? but directly route from host to tap interface ?
If yes,how do you setup guest configuration ?

Objet: RE: [PATCH] add routed network mode 

The last patch is just some experimental code. 

That is what I had in mind how a routed setup should work. 

I just created and tested a single VM here, and that works so far. 

What do you think? Is that nonsense, or usable? 
Any comments?
