I have the following setup: linux client @ 172.16.10.68
linux gateway @ 172.16.10.69, ipsec tunnel to aws box #1, gre tunnel 10.254.0.0/30
aws box #1, ipsec tunnel from linux gw, ipsec tunnel to aws box #2, gre tunnel 1 10.254.0.0/30 and second gre tunnel 10.254.0.4/30
aws box #2, ipsec tunnel from aws box #1, ipsec tunnel to aws box #3, gre tunnel 1 10.254.0.4/30 and second gre tunnel 10.254.0.8/30
I have bird running OSPF on the linux gateway, aws 1, aws 2, and aws 3. ipsec tunnel from aws box #2, gre tunnel1 10.254.0.8/30.
example bird conf: protocol ospf MyOSPF { tick 2; area 0.0.0.0 { stub no; networks { 172.16.29.244/32; 10.254.0.4/30; 10.254.0.8/30; 10.254.0.0/30; 172.16.10.0/24; }; default cost 100; stubnet 172.16.29.244/32 { cost 100; }; interface "tun1"; }; }
What I'm trying to accomplish is to provide internet access to the the linux client from aws box #3 over multiple hops. With the current configuration I can ping GRE tunnel IPs just fine, but none of the ethernet interfaces on the AWS boxes. I am open to suggestions and recommendations.
