Please refer to my attachment for the firewall>>rules>>Lan
In the most casual look you can see various inconsistencies and redundancies in your rules. Some tips that can help you:
1) When you want to refer to your LAN, try to use the alias "LAN SUBNET" instead of description in ipv4;
2) You have multiple subnets? or was refer to a station when the field source 192.168.204.0/24 quotes?
3) Implement a firewall like 'prudent', ie, create rules only for what you want to pass on your LAN to WAN. By default, everything should always be denied.
4) Do you have a rule blocking connections from on high ports. However, almost every type of connection is originating from high port!
Review your firewall completely ... Who knows, a good start would you buy the book: http://pfsense.org/book
