dhcp and dual-homed filtering host
Hi!
In a lab network, I have a dual homed Debian host that should act as a
packet filter between the external ("untrusted") and the internal
("trusted") interface. The untrusted network is on eth0; the trusted
network on eth1. The host should assign IP numbers on the trusted
network via DHCP while not doing so on the untrusted network.
The Package description for dhcp-1.0.2-0.1 says: "This package only
supports DHCP IP assignment on one interface." So, this is fine with
me.
I proceed to install dhcp and created an /etc/dhcpd.conf with only a
single subnet statement for the trusted network. When I try to start
the dhcp daemon, I get the error message "No subnet declaration for
eth0 (192.168.130.38)", the IP being the one of the external
interface.
When I add an empty subnet declaration ("subnet 192.168.131.0 netmask
255.255.255.0 {}") to /etc/dhcpd.conf, I get "The standard socket API
can only support hosts with a single network interface", which is
substantially different from the restriction the Package file
mentions.
Am I missing something? How can I get this dhcp into business?
Greetings
Marc
