If I understand what you are trying to do, you can try bridging, but I 
don't know if it will work the way you want it to or not.



The topology is one tunnel between two linux boxes:
-- eth1-|__|-eth0 <-> eth0-|__|-eth1 --

I'm trying now with:
ip tu add tun1 mode gre local loc.IP remote rem.IP ttl 255 dev eth0
ip addr add tun1 0.0.0.0 
ip link set tun1 up


Bring your tunnel up like you are, with IPs on each end.  Then bridge 
the tunnel interfaces with their local ethernet interfaces at each end. 
 In essence you are bridging your local ethernet segment with a common 
element, the tunnel, and thus together them selves.

[LARTC] Unnumbered GRE tunnel

[Pullus Cuetlachtli]

Hi!
Can I create the unnumbered GRE tunnel with iproute2 utility?
Can someone provide me a link/howto/example_config how to do it?
The topology is one tunnel between two linux boxes:
-- eth1-|__|-eth0 <-> eth0-|__|-eth1 --

I'm trying now with:
ip tu add tun1 mode gre local loc.IP remote rem.IP ttl 255 dev eth0
ip addr add tun1 0.0.0.0
ip link set tun1 up

but it doesn't succeed..
Thanks in advance for any help!
