Problem accessing a Wireguard SiteB (Site2Site tunnel) from W. remote client

[Itar]

Hi,

after hours of unsuccessful work, I would really appreciate some help/tips (in which direction to look).
I'll try it first with a rough configuration description:

I have two pfSense (2.6.0). They are connected via Wireguard Site A to Site B (like in this doc: https://docs.netgate.com/pfsense/en/latest/recipes/wireguard-s2s.html). I can access each other's lans from both sites without any problems.
I have also set up another tunnel for external devices (notebook,...): https://docs.netgate.com/pfsense/en/latest/recipes/wireguard-ra.html. From a notebook I can reach site A (through WAN) without any problems (also all vlan's).
However, I just can't manage to access the lans of Site B from my notebook (of course, the lans of Site B are entered in notebook's “Allowed IP's”).
Before I switched to Wireguard Site2Site I had a OpenVPN Site2Site connection with the same configuration (notebook) and it worked without any problems.
So I don’t know, if this is a misconfiguration, a limitation or a bug.

Solved, was a misconfiguration. I forgot to enter the IP-Range of the remote tunnel (notebook) at Site B (allowed IP's)
