Re: [vserver] ipvsadm and ip_forward

Hi Dennis, I didn't try what you want to do yet (it's in something like the
stack of todo tasks ;) but I needed when implemented vservers here to set up
a dummy interface, I think this could help you. I've tried to schemes: the
vserver host on the lan and vps guests on a private lan with the host as
gateway/firewall. The another is connecting out the host and the guests into
the same lan, all of them at the same level. In this last case the host is
still the firewall for the others but there's no network isolation. The
dummy interface in the first case, exists for the host and have one extra ip
for every guest you have. In the second, no dummy ip for the host is needed,
so they are only setup for the guests.
If you need some examples, I can send you some lines.

Regards,
Gustavo
