Hello,
I have a VM where I would like to setup a secondary interface which
has an IP on a remote lan ideally with GRE. I have a simple GRE tunnel
from dom0 to a cisco at the remote site, the tunnel works great I have
routes in and I can ping between both sides dom0 and the remote
router/lan. I had planned on just bridging the GRE interface with a
new empty bridge then have the VM attach to that bridge as well and I
would have ethernet over GRE. I create the bridge and when I try to
add the GRE interface to the bridge I get "invalid argument". After
some googling I saw several things mentioning that this there was some
activity with ethernet over GRE in recent kernels apparently around
the time of 2.6.28. I am running debian squeeze as dom0 so i have
2.6.32 which I would assume has that code, yet I still cant'' do it.
When I try to add the GRE interface to the bridge I get this:
# brctl addif br0 tunnel
can''t add tunnel to bridge br0: Invalid argument6
In dmesg on dom0 I see this:
[964402.806362] br0: Dropping NETIF_F_UFO since no NETIF_F_HW_CSUM feature.
Has anyone been able to do something like this? I know I could
probably put a different private lan on the bridge and nat it behind
the GRE interfaces IP but I think bridging would be cleaner and more
what my needs are.
Any info / ideas would be appreciated
chris
