172.27.26/24

172.27.26.0/27 (Ubald, home network)

If you need to assign a static IP in this range, use the following information:

• IP: an IP not in the list below, up to 172.27.26.14
• Gateway: 172.27.26.1
• Broadcast: 172.27.26.31
• Netmask: 255.255.255.224

If not, you will receive by DHCP an address between 172.27.26.15 and 172.27.26.29, with a resolve in tree-<number>.lostwoods.drake.

DHCP configuration

Offers DHCP from 172.27.26.130 to 172.27.26.158. 29 slots are so available.

Static configuration

If you configure a static IP on this range:

• Pick a free IP between 172.27.26.130 and 172.27.26.158
• Gateway is 172.27.26.129
• Broadcast is 172.27.26.159

Larger events

For larger events, the IP range is reserved to Drake peers, which then provide more broad access on their own block.

Free blocks

• 172.27.26.64/28
• 172.27.26.80/28
• 172.27.26.96/28

• 172.27.26.160/28
• 172.27.26.176/28

Link drake27 and drake26

An experiment to link Drake27 / Nasqueron and Drake26 / Lost Woods portions of the Drake network is ongoing in September 2024.

On router-001:

   INDEX=26
   DESCR=drake27_to_drake26
   
   TUNNEL_SRC=<IP configured on router-001>
   TUNNEL_DST=<IP configured on Ubald>
   
   LOCAL=172.27.27.251
   REMOTE=172.27.26.30
   
   REMOTE_RANGE=172.27.26.0/27

   ifconfig gre$INDEX create
   ifconfig gre$INDEX tunnel $TUNNEL_SRC $TUNNEL_DST
   ifconfig gre$INDEX inet $LOCAL $REMOTE netmask 0xffffffff
   ifconfig gre$INDEX descr $DESCR

   route add $REMOTE_RANGE $REMOTE

On Ubald, the OpenWRT router needs to be configured like this in /etc/config/network:

   config interface drake27
       option proto gre
       option zone drake
       option peeraddr <IP configured on router-001>

   config interface drake27_addr
       option proto static
       option ifname @drake27
       option ipaddr 172.27.26.30
       option netmask 255.255.0.0
       # Fixes IPv6 multicast (long-standing bug in kernel).
       # Useful if you run Babel or OSPFv3.
       option ip6addr fe80::42/64

The drake zone is configured in /etc/config/firewall:

   config zone
       option name 'drake'
       option input 'REJECT'
       option output 'ACCEPT'
       option forward 'REJECT'

   config forwarding
       option src 'lan'
       option dest 'drake'

   config forwarding
       option src 'drake'
       option dest 'lan'

Routing needs to be done with "ip route" and note with "route", as that last command is handled by busybox. Busybox source code will raise an error if we try to add a route for 172.27.27.0/24 via 172.27.27.1 as the gateway .1 belongs to the routed range:

   route del -net 172.27.0.0 netmask 255.255.0.0
   route add 172.27.27.251/32 dev gre4-drake27
   route add 172.27.27.1/32 via 172.27.27.251
   ip route add 172.27.27.0/24 via 172.27.27.1

Devservers and only devservers allowed to connect to Drake26 need a specific route:

   route add 172.27.26.0/24 172.27.27.1

It's not recommended to replace default routing for 172.27.27.0/24 (Drake27) by 127.27.26.0/23 (Drake26 + Drake27) or by 172.26.0.1/15 (All drake), as long as 172.27. is "trusted", ie as long as no firewall rule blocks traffic from outside 172.27.27.0/24 on every server.
