XEN Bridges with Debian

Ich verwende die folgende Netzwerkkonfiguration mit XEN:

• br0intern -> internal LAN (GREEN)
• br1extern -> WAN (RED)
• br2dmz -> DMZ (ORANGE)
• br3wlan -> WLAN (BLUE)
• br4off -> no network connection

File: /etc/network/interfaces.d/xenbridges

root@corsair:/etc/network# cat interfaces.d/xenbridges
# interfaces(5) file used by ifup(8) and ifdown(8)
# Included from /etc/network/interfaces

# settings for all XEN bridges
iface xenbridge inet manual
        pre-up brctl addbr $IFACE
        bridge_fd 0
        bridge_stp off
        bridge_hello 1
        bridge_maxwait 0
        bridge_waitport 0
        post-up ip link set $IFACE promisc off
        post-down brctl delbr $IFACE

# eth0 -> intern, the internal lan
iface br0intern inet static inherits xenbridge
        address 192.168.2.5/24
        gateway 192.168.2.12
        bridge_ports eth0

# eth1 -> extern, the internet/router
iface br1extern inet manual inherits xenbridge
#        bridge_ports eth1

# none -> dmz, firewall-zone only
iface br2dmz inet manual inherits xenbridge

# wlan -> eth3 or none=firewsall zone
iface br3wlan inet manual inherits xenbridge
#        bridge_ports eth3

# none -> offline zone
iface br4off inet manual inherits xenbridge
