Hi Guys,
Here is our patch to allow broadcast packets over a GRE tunnel.
Hopefully it might be accepted into the source someday.
You need to enabled bridging and GRE tunnels in your kernel. No other
options are required. The gre patch determines what type of protocol
type to put in the GRE header based on the whether the packet is
forwarded from a bridge or not.
To use the patch:
# Create your GRE tunnel
ip tunnel add gre1 mode gre remote 10.4.4.1 local 10.4.4.2
ifconfig gre1 up
# Bring the ethernet device up
ifconfig eth1 up
#create the bridge and add the devices:
brctl addbr br0
brctl addif br0 gre1
brctl addif br0 eth1
ifconfig br0 10.4.1.1 netmask 255.255.255.0 broadcast 10.4.1.255
regards
