Hello misc@,
I finally got around to setup a dhcpd in my local LAN.
All hosts get their IP by dhcp, but also need an alias (as secure VPN
inside LAN) on each interface, after playing around with
"/etc/hostname.<iface>" I found the place to put the stuff:
/etc/dhclient.conf. Seemed to work well until I tried it on my laptop
having two ifaces (wired and wireless).
As soon as I define several alias { ... } statements in dhclient.conf,
following dhclient.conf(5) (alias must be _outside_ interface "<iface>"
{...} statements), I receive errors. Here is exactly what I did:

I hope someone can help me or point out what I did wrong.
