Hello... I'm new here and looking for a way to implement an overlay network for management of serveres that I have all over the place, without having to open firewalls everwhere I look 🙂 I have been testing Netmaker extensively last week, and especially the capability to overcome NAT and firewalls has been challenging. The NAT holepunching feature seems to rely only on uPNP in a firewall. And I do not control most of the firewalls that I have servers behind, so that really is not an option for me. The NAT solution that works all the time is assigning a relay node to a "hard to reach" node. I have a few questions regarding this that I hope the community here has experience with and can demystify: - Can I assign multiple relay nodes to the same node? I would like this for redundancy purposes. It seems that I can set this up, and the graph in the server does show the correct topology (showing a nodes hanging off 2 relay nodes). However, there is NO connectivity between any of the nodes in the network, until I remove one OR the other relay. Is this a bug or working as intended? - I realise that the way redundancy for the server works, if either by setting up a redundant loadbalancer + 2 or 3 instances of netmaker-server and a redundant database. And since it seems the network pretty rapidly stops working when a server is down, here is no way around a redundant server. Can I still select a redundant server as a relay and that way create a redundant relay node in the network?

Hi @some-eye-54667, thanks for joining the Discord: 1. In general, there is not a way to set up redundancy for routes currently, whether that's via relays or via multiple servers. We have roadmapped setting up some form of redundancy, but this is probably a ways off. 2. We have talked about implementing ACL groups, but again this is probably a ways off. 3. Automatic relay selection is something we are implementing in the pro version, which should be in place within the next several weeks.

Thanks for your quick response. Great feedback. I realized that I came barging in the server and started pointing at all the stuff that was not working for me. It did not show my appreciation for the project and how far it has actually come already. It is excellent already for my personal stuff, and just really want to use it for managing our servers that are shattered about, while maintaining security. Would I be able to create a redundant relay by making a HA Netmaker Server a relay? Or what would happen if I made a HA Netmaker Server a HUB in a hub-spoke type setup?

HA Netmaker only makess the server API HA. The netmaker "nodes" (netmaker-1, netmaker-2, netmaker-3) operate like independent netclients, so those would not be HA.

Thanks for clarifying that... I'm not in doubt that it is not so easy to implement as it would seem. It probably requires some sort of routing protocol, which is not really needed when sticking to a none redundant infrastrucure
