If you do not want your proxy server to listen on the kernel loopback interface (127.0.0.1), you can easily fix this by configuring your proxy server to only listen on an IP address.
Just like mysql and other daemon processes, you can configure it to listen on 127.0.0.1 or not.
For example, many people configure mysql to only listen on 127.0.0.1 because they do not want any external connections to mysql; and 127.0.0.1 does not permit external connections.
If you don't want your proxy server to listen on 127.0.0.1, then you simply configure your proxy server to not listen on 127.0.0.1.

We are deploying an app to our students that is running as a daemon. It keeps them from using certain software. The problem is that when we initially deploy it we don't want to require a restart.

systemd-socket-proxyd
SYSTEMD-SOCKET-PROXYD(8) systemd-socket-proxyd SYSTEMD-SOCKET-PROXYD(8)NAME
systemd-socket-proxyd - Bidirectionally proxy local sockets to another (possibly remote) socket.
SYNOPSIS
systemd-socket-proxyd [OPTIONS...] HOST:PORT
systemd-socket-proxyd [OPTIONS...] UNIX-DOMAIN-SOCKET-PATH
DESCRIPTION
systemd-socket-proxyd is a generic socket-activated network socket forwarder proxy daemon for IPv4, IPv6 and UNIX stream sockets. It may be
used to bi-directionally forward traffic from a local listening socket to a local or remote destination socket.
One use of this tool is to provide socket activation support for services that do not natively support socket activation. On behalf of the
service to activate, the proxy inherits the socket from systemd, accepts each client connection, opens a connection to a configured server
for each client, and then bidirectionally forwards data between the two.
This utility's behavior is similar to socat(1). The main differences for systemd-socket-proxyd are support for socket activation with
"Accept=false" and an event-driven design that scales better with the number of connections.
OPTIONS
The following options are understood:
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
--connections-max=, -c
Sets the maximum number of simultaneous connections, defaults to 256. If the limit of concurrent connections is reached further
connections will be refused.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
EXAMPLES
Simple Example
Use two services with a dependency and no namespace isolation.
Example 1. proxy-to-nginx.socket
[Socket]
ListenStream=80
[Install]
WantedBy=sockets.target
Example 2. proxy-to-nginx.service
[Unit]
Requires=nginx.service
After=nginx.service
Requires=proxy-to-nginx.socket
After=proxy-to-nginx.socket
[Service]
ExecStart=/lib/systemd/systemd-socket-proxyd /tmp/nginx.sock
PrivateTmp=yes
PrivateNetwork=yes
Example 3. nginx.conf
[...]
server {
listen unix:/tmp/nginx.sock;
[...]
Example 4. Enabling the proxy
# systemctl enable --now proxy-to-nginx.socket
$ curl http://localhost:80/
Namespace Example
Similar as above, but runs the socket proxy and the main service in the same private namespace, assuming that nginx.service has PrivateTmp=
and PrivateNetwork= set, too.
Example 5. proxy-to-nginx.socket
[Socket]
ListenStream=80
[Install]
WantedBy=sockets.target
Example 6. proxy-to-nginx.service
[Unit]
Requires=nginx.service
After=nginx.service
Requires=proxy-to-nginx.socket
After=proxy-to-nginx.socket
JoinsNamespaceOf=nginx.service
[Service]
ExecStart=/lib/systemd/systemd-socket-proxyd 127.0.0.1:8080
PrivateTmp=yes
PrivateNetwork=yes
Example 7. nginx.conf
[...]
server {
listen 8080;
[...]
Example 8. Enabling the proxy
# systemctl enable --now proxy-to-nginx.socket
$ curl http://localhost:80/
