FTP connection to VIP do not established

run on different CLI windows:

 

 

tcpdump -nni host 10.155.65.26 and host

 

-----to filter out traffic to that IP and specific port (virtual server).

 

 

tcpdump -nni host and host

 

 

------to wacth the comm. between the client IP (snated) and the server.

 

 

then create an FTP connection and see what happens on both windows. After you detect failure or FTP gettin' stucked , stop tcpdump with ctrl-c

 

 

Then looking at both outputs you may find whether the server or client are stopping because a reset or something.

 

 

hope this helps!
