Configuring multiple bridges for eth1

[imuhim]

So I have a little of a unique problem. Before I begin here is my /network/interfaces file.

root@host:~# cat /etc/network/interfaces
# network interface settings
auto lo
iface lo inet loopback


iface eth0 inet manual


iface eth1 inet manual


auto vmbr0
iface vmbr0 inet static
        address  216.xx.xx.18
        netmask  255.255.255.248
        gateway  216.xx.xx.17
        bridge_ports eth1
        bridge_stp off
        bridge_fd 0


auto vmbr1
iface vmbr1 inet manual
        bridge_ports none
        bridge_stp off
        bridge_fd 0

I have two ip blocks 216.xx.xx.16/29 and 66.xx.xx.80/29. The first one: 216.xx.xx.16/29 I want on vmbr0, it works fine, because eth1 is bridged to it.

Now what I want to do is be able to have the second subnet: 66.xx.xx.80/29 on vmbr1 be connected to the internet. I think the solution has to do with some routing rules, but I still don't understand what that entails.

The reason I want to different interfaces for these subnets is so I can have dhcp assign the IP addresses so I don't have to go into the VM and do it manually (I already have that bit working).

I apologize if this has already been posted. I have been trying to figure out this problem for quite some time, so I figured the best idea was to post it on the forums.

Thanks!
