-------------------------

my problem is :

1- in the internet facing interface destination tab (IN) shows the public ip of the interface as a destination IP address   with a large data traffic , and as a reflection the local lan interface destination (OUT) shows the public ip of the interfacing interface as a destination (OUT) ? i cant determine what client receive this data ?

2- in conversation tab all the destination (OUT) of the lan interface shows the public ip address of the internet facing interface !!

can any one help me with that ?
