It seems that you did something wrong in ufw, but generally you are much better off running shorewall as firewall as it is so much easier to configure.

Copy that. I went ahead and got one setup and it actually works, all devices are making use of the 44net IPs and they all have direct internet access for inbound and outbound traffic, but I ran into a problem... The second I issue the "ufw enable" commend to bring up my firewall, everything stops working, no more traffic flowing in either direction. What can I do to fix this? I'm not great at Linux networking, I'm still learning it.

I don't see why you can't use a DHCP server locally, but there's a
caveat in that, for the gateway at 44.0.0.1 to pass traffic, your
addresses must have A (name) records in the ampr.org DNS domain. This
implies that the addresses handed out by DHCP are going to be
relatively static (unless, I guess, you register a bunch of names in
DNS in advance).

BUT, if all you want is a central place to configure address
information, then most DHCP servers can be configured to hand out
static addresses to specific devices identified by MAC addresses.
