Some weeks ago, I posted something like this on this list: This is the way I do networking with several UMLs on one host.
hydra:~# iptables -t nat -L -n Chain PREROUTING (policy ACCEPT) target prot opt source destination DNAT all -- 0.0.0.0/0 195.230.xxx.yyy to:10.0.0.10 Chain POSTROUTING (policy ACCEPT) target prot opt source destination SNAT all -- 10.0.0.10 0.0.0.0/0 to:195.230.xxx.yyy where 10.0.0.10 is the IP inside the uml machine (tap0 on the host has 10.0.0.1) and 195.230.xxx.yyy is the hosts second external IP. The disadvantage is, that inside the uml machine you see a different IP than outside. It also works for several uml machines on the host (even talking to each other) where everyone has its own external IP. You also can access the host with its IP without any interferences from the umls... ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
