I got this working.
I had way too many rules it seems, I followed a tutorial when I set things up that told me that for every rule I create on one interface like LAN I had to create the mirror on it's destination. I just disabled half my rules and everything is running fine.
To opt out the one device I made one rule:
Pass, Interface=Wireless, Source=Singlehost-192.168.25.45, Destination=any, Gateway=WAN
No extra NAT rules or anything else and it works great
