Cables

We need uplink connectivity and power at the nodes. Unsure where we can get that from. Worst case we have to lay cables all the way to the lab (roughly 100m).

• Network cable
  • Do we need "outdoor" cable?
  • Normal Cat6 cable, shielded: [1] ~37€ / 100m
  • Outdoor cable unshielded: [2] ~50€ / 100m
  • Outdoor cable shielded [3] ~140€ / 100m
  • Ubiquity Touch Cable [4] 130€ / 300m
• Power Cable
  • [5] 65€

Installation

• Futro S550 as VPN Offloader
  • Only one NIC
  • WAN on "VLAN 1", FF Client Network on VLAN 10

kreativquartier02

Temporary replacement for "kreativquartier01" while it's broken (🙈). VirtualBox VM running on Docker01

Messed up the name, but it should work nonetheless

VLAN Config

Most Guides suggest the following:

root@kreativquartier02:~# uci set network.client.ifname='eth0.10' 'local-port' 'bat0'

But that fails. Do the following instead:

root@kreativquartier02:~# uci add_list network.client.ifname='eth0.10'
root@kreativquartier02:~# uci commit network
root@kreativquartier02:~# /etc/init.d/network restart
