Hello, I have three subnets in my network. I wanted to give addresses on the LAN and WLAN networks by a DHCP server but my DHCP server is on a third subnet. So I used a DHCP relay.
The problem was that I did not found any documentation which explains how to configure the ISC's DHCP server. The man page is not very clear, but still usable. Finally, I succeed ! Here is a sum up of my configuration : 1. My network has 3 subnets (LAN, WLAN, DMZ) 1a. The DHCP server (Gentoo) is in the DMZ 1b. LAN & WLAN get their addresses using DHCP 2. The DHCP Relay is on my router 2a. I used "DHCP Forwarder" (http://www.nongnu.org/dhcp-fwd/) 2b. Its configuration is (relevant parts only) : if vlan0 true false true # LAN if eth1 true false true # WLAN if vlan2 false true false # DMZ name vlan0 lan name eth1 wlan server ip 192.168.3.22 3. The configuration of the DHCP server is (relevant parts only) : class "wlan-clients" { match if option agent.circuit-id = "wlan"; } class "lan-clients" { match if option agent.circuit-id = "lan"; } subnet 0.0.0.0 netmask 0.0.0.0 { pool { range 192.168.2.100 192.168.2.200; allow members of "wlan-clients"; option routers 192.168.2.1; } pool { range 192.168.4.100 192.168.4.200; allow members of "lan-clients"; option routers 192.168.4.1; } } What do you think of this ? -- Nicolas MASSÉ Pour récupérer ma clef GPG: gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 0x2A18C433 Key fingerprint: 6621 FC23 5DC7 54BA B952 316A 50B1 BC3F 2A18 C433
