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

[Alexandre DERUMIER]

>>I posted my code to make it clear what I talk about. 

So, for your setup, why not simply do a standard bridge setup + proxyarp ?

host config:
-----------
auto vmbr0
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1
bridge_ports eth0
bridge_stp off
bridge_fd 0

 
guest config: (tap is on vmbr0)
---------------------------------
iface eth0 inet static
address 192.168.1.3
netmask 255.255.255.0
gateway 192.168.1.1


echo 1 > /proc/sys/net/ipv4/conf/tap/proxy_arp
echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp


provider router(192.168.1.1)----------eth0---proxmoxhost(192.168.1.2)-vmbr0----------tap 192.168.1.3

Proxmox is routing, from tap to eth0 in above example. 

And this is by sure not bridging - you will see the difference when you implement a iptable firewall ;-)

I posted my code to make it clear what I talk about.
