However, I cannot SSH into my container from another computer on the local network -- it is only accessible via the host machine.  If I try to SSH from another machine, it says "no route to host."  Additionally, the container does not have internet access.  If I try to ping, use wget or apt, I get connection errors.  I'm assuming these two problems are related.

The host's etc/network/interfaces file sets up the five ethernet interfaces (eth0-eth3 with static IPs and eth4 with DHCP from the cable modem) as well as the bridge for lxc.  The following is my bridge entry:

it sounds to me like there really is "no route to host" ... the bridge
is isolated from the other physical cards (ie, all other hosts), and
there is probably not a route in the kernel providing access between,
or access to the outside -- only the host can see the bridge
interface.

whats is output of `ip route` or `route -n`?  do you have dhcp running
on the bridge or is the LXC host assigned a static ip?
