Question

hi,

1. We have a RUT300 behind a router (avm fritzbox). The router have a random public IP.
2. The other side is another firewall (opnsense) with an static public IP
3. Firewall-Rules are temporary on both sides "all allow" and "from and to all"
4. IPsec tunnel is up and running
             peers: static public IPs (opnsense) and dyndns-record (RUT300)
             nat-traversal is activ
5 problem:

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)

We don't find a solution. 

Can you help, please?

Best regards

Hello,

Could you provide a topology picture of your network with devices LAN IPs?

If I understand correctly, IPsec is configured within RUT300? I would like you to attach a troubleshoot file to your question. Please, replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there.

Best regards,
