Hi all,

We want to use firewalk, it is installed and can be launched.
We tested it on router first, access-list is applied on the interface connected to the PC from which we launched firewalk (only FTP is allowed ).

The architecture is as follow

PC_firewalk ( --- F0/0_Router ( ---- F0/1_Router ( -------- LAN_PC (

We used the following command "firewalk -pTCP 2"
We tried to change the metric, use the IP of LAN_PC.
We always get the following result

total packets sent : 0
total packets caught : 0
total ports scanned : 0
total ports open : 0
total ports unknown : 0

Could you tell what should be the command to use so that we can see the allowed ports.
