Terry,
I've had a Brother laser printer for a few years. It's their cheapest,
monochrome, single sided. I've always found the text to be not quite
dark enough, but OK for home use. The Brother provision for drivers on
Linux was patchy then but seems OK now. I wrote this list entry in Feb
when I couldn't scan:
"At that point I had THE obvious thought - is there a new driver?? Lo
and behold, on the Brother website is a packaged set of drivers for
printer, CUPS, and scanner - dated 21/8/2021!"
and all is well now. I also use a fixed IP address.
Regards,
John

The Webserver is also a DHCP Server and a DNS Server. The bottom
100 addresses are reserved for devices that a permanently
connected, eg river system etc. The top 100 or so addresses are
allocated to a user (eg a Visitor) by the DHCP Server. As soon as
the user's device is connected to the WiFi network, nodogsplash
routes his browser to the Webserver.
In other words, when a Visitor connects to the site WiFi he gets a
landing page on his device which allows him to choose the content
he wishes to view.
And is this borne out in the testing? Does the Visitor's device get
issued with an address in the expected range under both the working
and non-working scenarios? Does it also get told about the same DNS
server and default gateway (if any) in each case?
Does the Visitor's device obtain any unintended Internet access at
all?

Yes. In both scenarios the Visitor's device gets an IP Address and is told
about the DNS Server and default gateway, which is the Webserver. What
doesn't work is the script that points the Visitors Web Browser to the landing
Page.
Since I originally posted this, things have moved on. Yesterday I experienced
several instances where the system worked with the link to the VPN Server
connected and a couple when it didn't when it wasn't. I've been in contact
with the author of pistrong and he got me to capture some Webserver data in
both scenarios and we both came to the conclusion that the link to the VPN
Server was a red herring; the problem lies with nodogsplash.
This used to occur very rarely in the original installation (including before
the VPN Server went in), but now it seems to be worse. That is what I am
looking at now.
Does the Visitor's device obtain any unintended Internet access at
all?
No. The only Internet access is in the initial stage when requests from the
client devices to certain Google Servers are passed on to allow the device to
'see' the WiFi Network as a valid network and not a walled garden. Once the
connection is established the the Visitor's device is issued with a token
which provides access to the WMT content, but blocks access to the Internet.
