Die Seite wurde neu angelegt: „ = Setup dev environment for Opennet Firmware = We want to have a dev environment for Opennet fir…“

Neue Seite

= Setup dev environment for Opennet Firmware =

We want to have a dev environment for Opennet firmware development.

What do we need?

* 2x UGW AP (virtual x86)
* 2x User AP (virtual x86)
* 2x Clients


= Network structure =

see [[net-diag.drawio|file]]

networks:
* internet (with NAT; also for admin access later on)
* mesh
* br-lan (for each AP)
* mgmt (for ssh/web access)


= Setup virtualization infrastructure =

Install kvm + quemu + virt-manager.

Create networks:
* “default”
** virbr0
** 192.168.122.0/24
** NAT for Internet connection
* “network2-mesh”
** virbr1
** mesh
** 192.168.100.0/24
** Open network
* “network3-mgmt”
** virbr2
** additional interface on AP (for ssh/web access)
** 192.168.101.0/24
** Open network
* “network4-devnull”
** virbr3
** connect all br-lan here when br-lan is not needed
** Open network, 192.168.110.0/24, no DHCP
* “network4-lan0XY” (011, 021)
** virbrZ ( 4, 6)
** br-lan for AP0XY (011, 021)
** Open network, 192.168.1XY.0/24, no DHCP
