[SOLVED] S2S OpenVPN - Firewall issues

[greY]

Hi folks,
I have a site 2 site vpn between two OPNSENSE boxes. The connection itself is up and running.  My issue is that I cannot access each site from the other.

The server side configured firewall is like this


The firewall monitoring (server) is still showing some blocks


I don't understand this behaviour. What's wrong here?

--> fixed it by disabling IPV6 and allowing "Dynamic IPs" on Server
