Is it possibile PXE process on 1st NIC card and set up 2nd NIC card for Internet accessable?

Hi experts, this is my first post here and I am also new for foreman software recentlly. Sorry first if question is not smartable.

I install foreman server all-in-one in a VM instance with two NIC cards.
1st NIC: (usage only for PXE purpose and without gateway setting for access other network)
2nd NIC: (real Internet accessable subnet)

I have also edited Administer > settings
General tab > Foreman URL >
Provisioning tab > Unattended URL >

There is antoher target VM with two NIC cards for testing. I have configured foreman-discovery and boot up target VM via foreman discovery. However, during discovery step, target VM failed to response to foreman server.

My question is, can I achieve this scenario? If so, What settings did I configure wrong?

Expected outcome:

  1. target VM boot from 1st NIC card and install OS no matter via 1st or 2nd NIC card is fine.
  2. Once target VM OS installation done, assign IP for its 2nd NIC card

Foreman and Proxy versions:
Sorry, I do not know how to dump those message. I just follow Foreman 3.2 manual, so it could be version 3.2 ? Or how should I get those information?

Foreman and Proxy plugin versions:
version 3.2 ? Or how should I get those information?

Distribution and version:
PRETTY_NAME=“Debian GNU/Linux 11 (bullseye)”
NAME=“Debian GNU/Linux”
VERSION=“11 (bullseye)”

Hi! This is caused by Foreman Discovery Image (FDI) not bringing up all interfaces by default.

You can append fdi.initnet=all kernel argument to the FDI kernel line in the appropriate Discovery template, or you can remaster the image to bake it in and make it default.

See chapter 3.5.1 of FDI docs
