Hello!
I am trying to do some tests with tunneling, but I can see the GRE
packets incoming, but in a wrong interface...
My config:
ip tunnel add tunnel0 mode gre remote REMOTE_INET_ADDRESS local
LOCAL_INET_ADRESS ttl 255
ip link set tunnel0 up
ip addr add 172.16.1.1 peer 172.16.1.2 dev tunnel0
ip route add 172.16.1.0/24 dev tunnel0
This config is made in one side of tunnel, in a linux box. This linux
box is behind a router. This router is forwarding all gre traffic to a
ethernet interface of the router. Here is the ifconfig:
eth0 Link encap:Ethernet HWaddr 00:80:5A:61:5B:11
inet addr:192.168.21.39 Bcast:192.168.21.255 Mask:255.255.255.0

I can see the GRE packets on eth0, but I can't see on tunnel0 how can I
do to redirect gre packets to tunnel0 ??
Thank you!
