Hey,

currently I'm facing some problems with my new setup. Heres my setup.

Now I have some problems with my IPv6 connection. In first place everything looks fine but my Gateway-Monitor in my Opnsenses deliver continuesly 100% package lost. But when I try to make an nslookup or a ping with ipv6 everything looks good and there is no error in the output. When I try to connect to the internet via IPv6 with one of my containers in the vnets everything looks good as well. When I try to access my machines from the internet over the load balancer sometimes I get an connection error. It seemed that this only appears on my IPv6 connections. So I think that I have an error which I could not see directly.

Here are some screenshots of my Interfaces-File. The file looks exactly the same on both PVEs (exp. the ip addresses for sure). I already compared my full opnsense configs to each other and here are the settings the same as well (exp. ip-address range)

I dont use Tracking Interfaces with my public IPv6 subnet because I would create an failsafe environment. If I set IPv6-Adresses from both of my Inetnet Connections to the clients in the vnets I could potentially get connection problems when one of the opnsense or the pve dies.

Hope that someone could see the problem.
