This only complicates many things and creates too much overhead on such a slow connection.

# It consists of shinobu as a router (this configuration),
|
||
# connected to a TP-LINK TL-SG105E “smart managed” (i.e., it can do VLANs) 5-port switch.
|
||
# The upstream comes (for now) from a PŸUR “WLAN-Kabelbox” (Compal CH7467CE).
|
||
# Sadly, I could not enable bridge mode on it, so the packets now go through (at least) three layers of NAT:
|
||
# device → NAT on shinobu → NAT on plastic router → PŸUR CGNAT
|
||
#
|
||
# Because the switch only supports GbE,
|
||
# the two clients I currently have with support for 2.5GbE are connected
|
||
# directly to the two remaining network interfaces on shinobu.
|
||
# Once I have more devices with support for 2.5GbE
|
||
# or I find a good deal on a matching switch,
|
||
# I will change this.

# Wireless is configured by providing the whole hostapd configuration file as a secret.
|
||
# Once nixpkgs PR 222536 is merged, I will migrate to using the NixOS module.
|
||
# Thanks to Intel’s wisdom, it’s not possible to use 5GHz in AP mode.
