Multimaster connection through AWS VPN

[Rafael Rey]

Hi,

I've tested the package in a local network and it works like a charm. Now I want to connect two ROS Masters in two different geographical locations, using a VPN Server (AWS VPN for example).

I have two machines connected to the VPN, I can do ping and ssh between them so they can see each other, multicasting and ip forwarding are enabled in both machines. However I don't have ping to 224.0.0.0 (Maybe the problem is there)

Has anyone tried it or some similar setup like Peer-to-Peer (WireGuard) ? If so, which settings I need to take care of?

Hi, thanks for using and for the praise!

we have already tried it out successfully with zerotier vpn.
Perhaps you need to set the multicast route to VPN interface, e.g.: sudo route add -net 224.0.0.0 netmask 224.0.0.0 vpn0

Otherwise you can try without multicast by setting the ~robot_hosts parameter of the master_discovery.

Thank you for your fast reply! We finally used the package without the multicast feature, as it's enough for us and it worked like a charm, both with Peer-to-Peer WireGuard VPN and Amazon AWS VPN :) Thank you very much
