I have tried running FreeBSD desktops several times over the years. It
was a lot of work and the experience was disappointing. As much as I
would like a FreeBSD desktop, Debian with Xfce is easier to install and
more Xfce features are supported.

It would be good for you to know the make and model of your antenna. I
suspect it functions as a modem.

While building your own gateway from scratch using a general-purpose OS
is a useful exercise, it is an ISP's worst nightmare. If they attempt
to support you, they will struggle. Most ISP's will simply refuse to
support anything except their own equipment.
I recommend that you buy or lease a residential gateway from your ISP,
connect it to the antenna, and get it working reliably (with or without
support from your ISP). Then, connect #5 in a router-behind-router
configuration (e.g. connect #5 to the LAN side of the ISP gateway). Now
you can play with #5 all you want, and you still have a working Internet
connection the whole time. This is what I do.

I keep a plain text administrator log file for every computer. I put
this file plus any system configuration files I create or modify into a
networked version control system (CVS). I recommend that you do the same.
Here is my log entry for a recent FreeBSD install. I recommend that you
take notes like this whenever you install; they are invaluable for later

I install 2.5" SATA mobile racks in my machines and have a stack of
small 2.5" SATA SSD's, with one OS instance per SSD. This makes it easy
to mix and match:
https://www.startech.com/en-us/hdd/hsb220sat25b
https://www.startech.com/en-us/hdd/s25slotr
The fact that the MAC address remains constant when I boot one computer
with several different OS disks can confuse DHCP and DNS caching.
Therefore, I try to limit myself to one computer when experimenting with
OS's and I use IPv4 addresses rather than host names when experiementing.
> --how_ever-- , when the user_machines are going through the 11.3 box ,
To get #5 working as a gateway, I recommend that you dedicate the
machine to that purpose and do a fresh install of
FreeBSD-12.3-RELEASE-amd64. Unfortunately, the FreeBSD installer UI
does not have an option to limit the amount of disk space used -- it
uses the whole disk. Get a small SSD, USB flash drive, or SDHC card
("16 GB" devices are more than adequate). Keep meticulous notes. Use a
version control system for your notes and any system configuration files
you touch. Use dd(1) to take raw binary images of the disk as you go,
so that you can easily revert changes.
