FTP Outbound Behind Load Balancer

Question

_{Tuesday, February 19, 2019 3:36 PM}

Hi all. I have two virtual machines with private IP sitting behind a load balancer with public IP. 

On the one machine I created a FTP site, and on the load balancer I have allowed an inbound NAT for port 21.

I am able to connect to the FTP site with FileZilla, unable to retrieve directory listing.

I am struggling to figure out how to allow outbound traffic from behind this load balancer within resource manger. Any help will be appreciated.

Thanks!

Hi Lourens, 

Once the FTP session is established, based on the mode you connect you need to create rules/inbound NAT rules for those ports that you have defined. 

For example, if you configure port 65520 to 65530 in Passive mode, then you need to create rules for those ports in Load balancer so that it forwards the traffic to the backend server.

Sorted thanks Msrini. Added Load Balancing rules which resolved the issue.
