iSCSI and docker network

Hello,
I have a proxmox node so I decided to add and iSCSI share to it. So I enabled the share on truenas - basic, no auth etc. Configured portal address to 192.168.1.25 (NAS IP). Then I configured proxmox and the share is visible there. However when I was checking proxmox logs I saw a lot of errors like this:

Oct 21 15:42:57 proxmox01 iscsid[2747]: Connection1:0 to [target: iqn.2005-10.org.freenas.ctl:proxmox, portal: 192.168.1.25,3260] through [iface: default] is operational now
Oct 21 15:43:12 proxmox01 iscsid[2747]: Connection-1:0 to [target: iqn.2005-10.org.freenas.ctl:proxmox, portal: 172.16.2.1,3260] through [iface: default] is shutdown.
Oct 21 15:43:12 proxmox01 iscsid[2747]: Connection-1:0 to [target: iqn.2005-10.org.freenas.ctl:proxmox, portal: 172.16.0.1,3260] through [iface: default] is shutdown.

The 172.16.x.x IP’s are the docker network IP’s related to the running apps. Not sure if I misconfigured something, but is it possible to stop TrueNAS from advertising docker network IP’s as an iSCSI targets? Or maybe this is an proxmox configuration issue?

It seems that there is a way to control the target portals visibility to initiators by setting allowed_portal attribute for the iscsi target:

echo ‘add_target_attribute iqn.2005-10.org.freenas.ctl:proxmox allowed_portal 192.168.1.25’ > /sys/kernel/scst_tgt/targets/iscsi/mgmt

It would be nice to have an option in GUI for that (or maybe there is?)
