** Description changed: 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 208.67.222.222 + 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.
