Ma tot uitam cum se salveaza pe ubuntu/debian reteaua configurata cu bridge

si .. iata in : /etc/network/interfaces se scrie

auto br0
iface br0 inet static
address 172.16.32.1
netmask 255.255.255.0
pre-up /usr/sbin/tunctl -t tap0
pre-up /sbin/ip link set eth1 up
pre-up /sbin/ip link set tap0 up
pre-up /usr/sbin/brctl addbr br0
pre-up /usr/sbin/brctl addif br0 eth1
pre-up /usr/sbin/brctl addif br0 tap0
pre-up /sbin/iptables-restore < /etc/iptables.conf
pre-up /bin/echo 1 > /proc/sys/net/ipv4/ip_forward
pre-up /sbin/modprobe nf_conntrack_ftp
pre-up /sbin/modprobe nf_conntrack_irc
post-down /usr/sbin/brctl delbr br0

pentru comanda tunctl este nevoie de pachetul uml-utilities
