Thank You for Your time and answer, Arno:
I think this setup might need additional configuration on the outside,
because you need to add the same subnet route on your Internet
modem/router. I don't think qemu gives you NAT for free...
I've got such a problem w/ NATing:
/sbin/iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -d !
192.168.1.0/24 -j SNAT --to-source 192.168.0.2
Bad argument `192.168.1.0/24'
Do You have any idea why iptables does not accept the ip nor the ip net?
Then I went this way for NAT-ing but w/ no luck:
iptables -t nat -A PREROUTING -i eth0 -s 192.168.0.2 -j DNAT
--to-destination 192.168.1.10
iptables -t nat -A POSTROUTING -i eth0 -s 192.168.1.10 -j SNAT
--to-source 192.168.0.2
iptables -A FORWARD -i eth0 -o tap0 -d 192.168.1.10 -j ACCEPT
Also, on host I do:
sysctl -w net.ipv4.ip_forward=1
route add -host 192.168.1.10 dev tap0
and on guest:
route add -host 192.168.1.2 dev eth0
route add default gw 192.168.0.2
