NSX-V FTP Load Balancer

[sguadamu1]

Hi NSX experts,

I am trying to get some help since I am not able to set up an LB using NSX-V for my FTP service. 

I am following a TOI presentation however I am seeing the following outouts:

Loadbalancer Pool Statistics:

POOL ftp-test
| LB METHOD round-robin
| LB PROTOCOL L7  <---------------------- even when acceleration is enabled.
| Transparent disabled
| SESSION (cur, max, total) = (0, 0, 0)
| BYTES in = (0), out = (0)
+->POOL MEMBER: ftp-test/member-1, STATUS: UP
| | HEALTH MONITOR = BUILT-IN, default_tcp_monitor:L4OK
| | | LAST STATE CHANGE: 2022-03-14 20:23:45
| | SESSION (cur, max, total) = (0, 0, 0)
| | BYTES in = (0), out = (0)

Also I have the ALG configures as 

allow any any and in service I selected FTP.

I took some packet captures at the pool member level and I can see when I bypass the LB the communication working fine, but when I use the LB the request does not even reach the pool, seems like it is not passing the ESG.

Best Regards.
