I don't know if it is what you want, but I'm using this: iptable-restore < my_iptable
where my_iptable is: *filter :INPUT ACCEPT [6242:8433725] :FORWARD ACCEPT [8802:8139455] :OUTPUT ACCEPT [4070:537046] COMMIT *nat :PREROUTING ACCEPT [54:3534] :POSTROUTING ACCEPT [0:0] :OUTPUT ACCEPT [1:60] -A POSTROUTING -o eth0 -j MASQUERADE COMMIT and /etc/qemu-ifup is: #!/bin/sh echo "Configuring $1" sudo /usr/sbin/tunctl -t $1 sudo /sbin/ip link set $1 up sudo /sbin/ifconfig $1 192.168.1.1 broadcast 192.168.1.255 netmask 255.255.255.0 And I configure the guest with IP 192.168.1.2 and gateway 192.168.1.1.
