[Babel-users] VPN Bridging with Babel

Tue Jun 18 16:00:37 BST 2019

Hi,

I've got a wireless mesh network that I'd like to bridge to a VPN
(using OpenVPN). The mesh is in 172.16.0.0/24 and the VPN uses
172.29.0.0/16. I've got one bridge node on the mesh running babeld
with tun0 and mesh0. The rest of the mesh nodes just run babel on
mesh0.

The VPN gateway is 172.29.0.1, and the bridge's address on the VPN is
172.29.0.6. It's 172.16.0.5 on the mesh. My trouble is that I can't
reach 172.29.0.1 from any nodes on the mesh but the bridge.

I assigned a link-local IPv6 address to the VPN gateway's tun0
interface, per the README, and made sure that the mesh nodes all have
link-local IPv6 addresses. Interestingly, the bridge's tun0 device
already had a link-local IPv6 address, probably because it's running a
newer version of OpenVPN.

All nodes are running babeld 1.7.0.

I sent SIGUSR1 to babeld on the bridge, and it gave me the large dump
of text at the end of this message. The log file on the bridge gets a
lot of these messages:

kernel_route(ADD): No such device

I can ping the VPN gateway from the bridge, but not any other nodes on the mesh.
