bridge

I have a ubuntu box setup with two NICs. I can bridge them together just fine, but I haven't been able to setup a way to SSH into the box once the connections are bridged together. Here's my /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth1
iface eth1 inet manual

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
    address 192.168.33.213
    netmask 255.255.255.0
    gateway 192.168.33.1
    bridge_ports eth0 eth1
    bridge_stp off
    bridge_fd 0
    bridge_maxwait 0

This works just fine for bridging, but I'm not able to SSH into the box. I tried setting up another interface on one of the NICs:

auto eth0:1
iface eth0:1 inet static
    address 192.168.33.215
    netmask 255.255.255.0
    gateway 192.168.33.1

But this really didn't help. Is it possible to ssh into a machine that has all of its NICs bridged? If it is, how?
