NOTE 
* WAN filters are not applied to the connections established before setting up them. 
* “Packet Detect Activate function” will establish a PS connection even when a packet to be 
dropped by WAN filter was made.  
WAN filters drop the targeting packet data after the PS 
connection is established.  Please use Packet Filter ([Sec. 6.5.5.2  Set Packet Filter  (p6-57)])  to 
restrict the establishment of PS connections by PDA. 
* WAN filters are not applied to the Ext WAN. 
* When there is a 1 by 1 NAT connection in the network of existing IP Masquerade connection, the 
WAN filter rules of the IP Masquerade 
will be applied to the 1 by 1 NAT connection as well as 
those of 1 by 1 NAT.
