We have pf running on the OpenBSD box. I plan to put the rules into a
git repository that we would accept pull requests on, for example for
people to do port forwarding.
I'm not sure yet if this will take the form of just having the files
there and a script that will copy them, or going full Ansible on it.

I am pretty familiar with BSD networking. If there are others that would
like to be involved in running the space network, I am happy to assist
them until they can do it on their own.
The OpenBSD manpages are excellent at describing the various options for
drivers (we are using em, trunk, gif, gre, and vlan).
We currently are using only static routes but once some dn42 peers have
tunnels we will start using OpenBGPD.

We shouldn't have everyone maintaining the device that provides everyone
with Internet. It should be stable, reliable, do the right thing when
you turn it off and on again, and generally not get in the way.

I too have had various Netgear switches and I know that the CLI isn't
the best. If there are TP-Link alternatives then we should look at
those. The problem we have is mostly the depth of the cabinet. Again
though, configuration changes should not be necessary on this switch
that often, it is providing a base infrastructure for others to build on
top of and should really just be forwarding packets.
Also, if someone already has a managed 1U 24 port switch that is not
that deep and would like to donate it, that would be super awesome.
We have a whole bunch of Cisco kit if people want to play, build test
networks, learn stuff, etc. If this switch is messed up then we can't
open the door so access should really be restricted.

If you're not already set up on dn42, you can take a look at the wiki.
