I'm trying to test tunneldigger by tunneling from one linux box to another (no mesh network involved). The tunnel itself seems to establish properly, but packets aren't routing as I expect them to.\r\n\r\nThe l2tp0 interface gets created on the client, and a corresponding l2tpxxx-xxx interface gets created on the broker. Once I bring both interfaces up `ip link set <if-name> up`, I can send pings into one interface and see ARPs come out the other:\r\n\r\n```\r\n# on the client\r\nping -I l2tp0 8.8.8.8\r\n```\r\n```\r\n# on the broker\r\ntcpdump -i l2tp101-101\r\n00:36:29.925663 ARP, Request who-has google-public-dns-a.google.com tell <client-ip>, length 28\r\n```\r\nThese ARPs don't seem to go anywhere else though. I must be missing some routing config to get these packets out to the internet. I guess I'm wondering, what's the minimum config (presumably in session hooks) I need to be able to test tunneldigger in this way?\r\n\r\nI guess this is more of a basic networking question than a tunneldigger question."}}
