Timotej Lazar 457ab7d3b7 Query prefixes once for all hosts
And group them into vrf_prefixes for VLAN networks and bgp_prefixes for
servers plugged directly into fabric.

This should reduce the number of queries to NetBox when configuring
firewalls and exit switches. Not sure but I think set_fact helps to
avoid queries (as opposed to setting group_vars).

Timotej Lazar 1c0709a6a6 fabric: allow all VLANs on bridge
Don’t try to guess what should be allowed because not all switch links
are tagged in NetBox. For now we limit mainly on access switches.

Timotej Lazar 2443a90bc5 fabric: use FHRP groups for virtual router IPs
More realistic- and supported-like and also avoids duplicated gateway
addresses.

Timotej Lazar db397cb2b1 exit: store VLAN interface addresses in NetBox
… instead of generating them from prefixes. A NetBox script can be
used to create and configure all necessary data for a new VLAN.

Instead of VLAN roles “inside" and “outside” we now create separate
VRFs for inside VLANs to match the actual exit/firewall configuration.
The “outside” VRF is for all VLANs that are directly accessible from
the internet.

Timotej Lazar ece3b8a377 exit: sort prefixes by family values
Because I made some seemingly unrelated changes in NetBox and they all
got flipped‐turned upside down.

Timotej Lazar 6dcae194d7 firewall: accept VPN connections from inside also
People tend to leave WireGuard tunnels active and we don’t want things
to become unreachable when moving to one of the inside networks.

Timotej Lazar c479f90669 access: move switch config templates back to this repo
Let’s keep it simple. Also editing templates in NetBox is a pain.

Timotej Lazar 7ef4023424 firewall: add known IP ranges in network ipset definitions
This data should only change in NetBox, so no point deploying it from
firewall master. Sometimes the first approach is the best approach.

Timotej Lazar aa82e5aa18 firewall_master: don’t define ipsets for VLAN groups
Was a harebrained idea from the start.

Timotej Lazar a97d133873 fabric: don’t set bond slaves if there are none
Not that that should happen except by mistake.

Timotej Lazar be0cc49b33 access: ignore more non‐changes
Should probably move this somewhere more listy if it keeps growing.

Timotej Lazar 27dac09549 access: move secrets to password store
Keeping ansible-vault values in NetBox is too cumbersome and limited.

Timotej Lazar f54b23f49a firewall: disable forwarding for mgmt interfaces in if-pre-up
Should be more robust and more importantly works when interfaces are
not renamed by mdev as is the situation now.

The mdev rules for renaming interfaces at boot seem to not work with
latest Alpine. So rename with ifupdown instead.
