You missunderstand how the rules work.

Rules:
Rules are processed from top to down.
If a rule catches the rest of the rules is no longer considered.
Per default a "block all" rule is always in place (invisible below your own rules).Traffic is filtered on the Interface on which traffic comes in.
So traffic comming in on the LAN-Interface will only be processed by the rules you define on the LAN tab.
A couple of reasons, my outside interface is using port 1194 the 12.166.84.3 ip is using 34246.
Each connection has a destination-port and a source-port.
Only the destination is 1194. The source can be something random between 1024+ ~ 65535.
