peers: static public IPs (opnsense) and dyndns-record (RUT300)
nat-traversal is activ
5.1. from the LAN network (192.168.55.0/24) behind die opnsense, we can ping the Remote LAN network (172.16.10.0/24)
5.2 from LAN network (172.16.10.0/24) behind the RUT300, we can not ping the Remote LAN network (192.168.55.0/24)
