I have followed the instructions on the wiki pages to the exact detail, and am having issues with the setup.  I am at the point where I can receive routing updates but cannot send any data over the tunnel.  I am not the best when it comes to Linux but have a better understanding of networking, routers, and routing (Cisco).

I have eth0 on a public address.

I have eth1 on 44.64.192.253/24

I have tunl0 on 44.64.192.254/8

I am running Ubuntu 10.04 on VMWare.

1. When I create the tunl0 interface with the class A netmask, how is rip44d using this and where does the tunnel “endpoint” get defined? (remote endpoint address?)

2. I have the Linux machine running rip44d and another linux machine on the same assigned 44.64.192.x subnet.  I can ping between them until I bring up the tunl0 interface.  If I down and up the tunl0 interface, I can ping as expected.  Can anyone explain this behavior?

3. The tunl0 interface is registering collisions equal to the number of packets transmitted.  I cannot find a reason why this is happening.

Thanks in advance,

Jesse
