Of course it works, because you just deactivated your firewall. 
Anything goes through it (all your rules in FORWARD chain have ACCEPT 
target, and than you changed default policy to ACCEPT: everything is 
accepted).

Also, it seems that you have (incorrect) assumption that packet will go 
through both INPUT and FORWARD chains (because you are catching "bad" 
packets only in INPUT chain).  Packet will go either through INPUT (if 
it is destined for local machine) or through FORWARD (if it is to be 
routed/forwarded to another machine).  It will never go through both.
