default deny rule matchs, and ignores wan rule

[Beleggrodion]

I have a strange issue on one of our firewalls. i found some nearly similar threads here in the forum, but the solutions their don't work. But it looks like a double-nat asynchronious routing problem, but im'm not the expert here.

On the router of the provider, i had a port forwarding for ipsec and also https and ssh.  (no source ip restrictions possible)

On the firewall i have the rule to allow all traffic from the source ip of our office to the wan interface.

But when i try to connect from the office, the "default deny" rule matches and the traffic is dropped.

I tried with the advanced setting of the rule and the state type "sloppy" and "none" but this don't have any effect.

Internet <=> Provider Router, 192.168.1.1 <=> OPNsense Firewall 192.168.1.128

All IP's are fixed.  Netstat on the firewall told me the following: (The ip's i x-ed are vpn ipsec networks, which currently also not work, the 192.168.9.0 net is the guest wlan)

A i was onsite to install the firewall on monday's the connections worked, but now not anymore without a change (until now which i tried with sloppy, and so on).
