How are you trying to access your resources? I see one issue:
push "dhcp-option DOMAIN 192.168.11.1"
You are pushing a DNS domain of 192.168.11.1 to your clients, so all of your name searches are being appended with "192.168.11.1" which is incorrect. The DNS Default Domain box in your config should have the name of your domain (e.g. MyDomain.com) in it, not an IP. Are you even using AD? If not, you shouldn't be pushing a DNS default domain.
I also see you have an AirVPN client tunnel configured. Is that new? I would modify the firewall rule on the OpenVPN tab, so it's explicit to your remote access tunnel network and your LAN. In other words, change the source to 10.0.11.0/24 and change the destination to "LAN net".
What do the rules look like on your AirVPN_WAN_HK tab? Hopefully, you don't have an any/any in there :)
Another question, what version of PFsense were you running on your old hardware? What version are you running now?
