Hi! I'm so sorry. The preconf services are full (by GNOME guide I must use 10
items max), and I think this isn't a commun issue.
Best regards mohan43u ;)

Bug description:
While set up a tun/tap network with Ubuntu as host and lfslivecd as guest in
Qemu, I got some problem. Here is the commands I used,
Ubuntu(host):
$ sudo qemu -cdrom lfslivecd -boot d -kernel-kqemu -m 512 -net nic -net tap &
$ sudo ifconfig tap0 192.168.10.1
$ sudo sysctl -w net.ipv4.ip_forward=1
$ sudo iptables -t nat -A POSTROUTING -j MASQUERADE
lfslivecd(guest):
$ ifconfig eth0 192.168.10.2
$ route add default gw 192.168.10.1
Both host and guest pinging each other properly.. but problem occurs when I
tried to ping opendns's default servers from lfslivecd.
lfslivecd(guest):
$ ping -c 3 208.67.222.222
3 packets transmitted, 0 packets received, 100% packet loss
After disabling 'gufw', everything worked. And I added opendns's nameservers in
resolv.conf
lfslivecd(guest):
$ cat > resolv.conf
nameserver 208.67.222.222
nameserver 208.67.220.220
It will be helpful if someone can write a rule to accept packets to go to Guest
Instances in the default Gufw rules setup. Is accepting packets for Guest's, a
security concern?
