Why does WireGuard only support 20 connections

[Patrick M. Hausen]

I supports only 20 instances. Each instance can support a multitude of separate connections to various endpoints. What's your reason to configure that many instances?

I do not know if this limit is in WireGuard or specific to the OPNsense implementation. I never needed more than 2 or three instances, though.

Its just a limitation of the early days where WG was unstable. I cant imagine where you need more than 10. Only if you use for every client a dedicated instance (for whatever reason)

I go from site to site and have many branches. Can you tell me how to remove this restriction?

[Patrick M. Hausen]

But you need just one instance and N endpoints to connect N branch offices to a HQ in a star topology ...

I have more than 100 branches with different IP network segments. How do I set them?

[Patrick M. Hausen]

All as endpoints with a single instance. You do not need a tunnel network! Just allowed networks and that's it.

Can this achieve interworking site?

Sure :)
