I have a gentoo server with to nics.

Just for an experiment i have added an alias to my eth1.
On this alias i want to attach dhclient as a dhcp server.

Now i have a working dhcp on eth1. But when i try to start this on eth1:1 ( after stopped the dhcp server on eth1 ) the program exits with an error.

No subnet declaration written for eth1:1 (0.0.0.0), please do so etc. etc.
And this while the subnet decl. is correct. (192.168.1.0 ) and the eth1:1 with an ip of 192.168.1.3. (checked with ifconfig).

It is clear to me that dhcp-client fetches the wrong ip (don't know how) 0.0.0.0 instead of 192.168.1.3.

Anyone tried this at home ?

Are you sure it isn't complaining about the subnet mask? If it is, it should be something like 255.255.255.0.

What does your /etc/conf.d/net file look like?

This is my ifconfig.

Can you try to post a bit more accurate information? For instance, in your first post, you talk about dhclient and dhcp-client. Neither of those are packages in portage. Are you referring to dhcp-agent, dhcpcd or ??? Additionally, it isn't clear in your message where you're referring to a dhcp client and where you're referring to a dhcp server.

Then, the IP addresses mentioned in your first and second posts are completely different. 192.168.1.3 vs. 192.168.1.251/2/3, etc.

Next, what is the *exact* error message that you are getting.

Finally, what is your entire /etc/conf.d/net file?
