Yes, that's how I was told to set it up by a helpful individual. I was told since it was one subnet, no routing would be needed. The wireless & wired interfaces would be bridged. Seemed reasonable. It sounds like you are suggesting exactly the same thing so "fundamentally broken" seems a bit harsh.

Key thing there is BRIDGED - ONE bridge interface with ONE address in the subnet, more than one port assigned to the bridge. What you have is NOT a bridged network, it is two SEPARATE networks with the same subnet - it's is fundamentally broken and will NOT work (at least without a lot of fudging around to work around the brokenness.

I've never setup a bridge before and got the syntax for brctl wrong
and that's what caused the config you saw. I thought I was telling
it to bridge wired & wireless faces, when apparently it was
doing something else without telling me so. I was doing: brctl
addif br0 enp4s5 wlp2s0 which I thought linked the two faces. It
apparently added the enp4s5 and ignored the wlp2s0.<br>
<br>
Once I finally realized that yesterday and corrected the syntax it
will not add the wireless interface as a port. <br>
<br>
# brctl addif br0 wlp2s0 <br>
can't add wlp2s0 to bridge br0: Operation not supported<br>
<br>
And just to be complete:<br>
<br>
# brctl addif br0 enp4s5 <br>
device enp4s5 is already a member of a bridge; can't enslave it to
bridge br0.<br>
<br>
# brctl addif br0 enp6s0 <br>
#<br>
That one succeeds, because like 4s5, 6s0 is a wired NIC.<br>
<br>
<br>
That's after changing "manuel" to "manual" just in case that was a
relevant issue.<br>
<br>
Therefore as I can't add the wireless face as a port, I'm unable to
bridge using brctl from the bridge-utils package. So unless there
is another virtual bridge package, bridging won't work. Unless of
course I'm still doing it wrong which is always a possibility.<br>

OK, so there's a different issue there, and it'll be to do with your masq setup.</pre>

You probably need to take a step back and get the basics working first. Forget your DHCP for the moment and statically configure some clients - that way you can work on one issue at a time.</pre>

I had everything working including DHCP except blue->Internet.
After getting that far by myself, someone redirected me to a
different setup that as you've pointed out, is broken, starting with
the bridging package itself (no wireless support).<br>
<br>
So proceeding further down this path is not possible afaik.
Therefore, also considering the fact that bridge-utils is considered
deprecated, I'm going to go back to my original setup of 2 separate
subnets and route them as I originally intended. I got sent down the
garden path, thanks for helping bring me back!<br>
<br>
There is apparently another way to do this using systemd I stumbled
on, but I have not looked into it, bridge-utils seemed to be the
fastest way forward. Sadly, it was not.<br>
<br>
Thank you for all your insight and help, it is greatly appreciated!<br>
<br>
By the way... do you (or anyone) know of a general networking
mailing list? Thanks again!<br>
