FTP Directory issue After WAN/LAN ROUTER UPDATE

Hello,
I recently had to upgrade my wired Router after the older model was failing. I have Forward the ports and I can gain access however when I do I see the followingl

Remote Site: /

.bash_logout
.bash_profile
.bashrc

Now I know enough that is not right. Also for the directory setting I see /mnt. I did attempt to change the directory setting to /var/flexshares/shares/mydirectory

I get this:
Status: Retrieving directory listing of "/var/flexshares/shares"...
Status: Directory listing of "/" successful

I am using Filezilla and the New Router is TP-Link ER605.
I would appreciate if someone was able to point me into the correct direction. I did forward the correct ports on the Router and Server. It all worked fine before the upgrade.

Any help would be greatly appreciated.

Thank you!
Bill
