Assuming you are testing with a single client IP that you know and that isn't SNATted then the CLI syntax would be something like;

 

 

tcpdump -i 'internal-vlan-name' -nn -vv host x.x.x.x

 

 

If you wanted to see the actual content of the packets at the CLI too then;

 

 

tcpdump -i 'internal-vlan-name' -nn -vv -s 0 -X host x.x.x.x

 

 

To write it to a file instead;

 

 

 

tcpdump -i 'internal-vlan-name' -nn -vv -s 0 -w /dir/filename host x.x.x.x
