    DHCP relay

    Hi,
    I have two routers (1st ASUS WL-500gP as main and 2nd ASUS WL-500W as second to WiFi connection as second VLAN) I have problem with dhcp relay from stations in VLAN (br1 resp. eth0) f.e.:
    ISP
    |
    [ASUS WL-500gP] - DHCP server
    |
    [ASUS WL-500W]
    |
    Stations

    Both routers include extended 1GB flash disks and installed ipkg (but I a not find any dhcprelay)

    Thanks for any replay to find any solution.

    Did you take a look at the dnsmasq man page?

    dhcp relay...
    you mean that the stations aquire the ip from the wl-500gp?
    I guess so...
    in that case you should insert the cable between the gP and the W in the LAN port of the W and not in the WAN...
    if you then disable dhcp on the W you should have it working

    DHCP relay like ip-helper

    It is not function solution - when I switch off the dhcp server on wl500w any dhcp request or answer will not go trough the router.
    dnsmasq will be rihgt way - but I feel like BFU :-(
    What I need?
    wl500gP (vlan1 10.1.1.0/255.255.255.0 - LAN )
    - in this sub-net is server 10.1.1.10 (it contains dhcp, dns)
    &
    wl500w (vlan2 10.1.3.0/255.255.255.0 LAN & 10.1.1.5/255.255.255.0 WAN)
    - in sub-net 10.1.3.0 I would like put forward all dhcp request to address 10.1.1.10 by the router.

    How I have to setup the dnsmasq.conf file to reach this function.
    Maybe I will have to study man-pages :-)
    Thanks for Your advice ;-)

    did you plug the calbe in the LAN1 port instead of the WAN port?
    it's working verry well over here

    but, what you asked specific here.... I have no idea tbh
    maybe someone knows in the wl-500gP part of the forums

    I try this configuration:
    wl500gP:
    ISP < 10.0.0.1 (WAN) <> (LAN) 10.1.1.1
    wl500W:
    10.1.1.5 (WAN) <> (LAN) 10.1.3.1
    dhcp request from subnet (10.1.3.0) really doesn't appear on WAN interface (tcpdump)
    I know that possible to make plane-net - (wl500w set as only switch) but a would like to make an isolation sub-net (for broadcast packet) in this micronet are in most cases widozes. In first sub-net (10.1.1.0) are *nix machine :-)

    hmm... I have no idea how to do that mate, sorry
    I'm not really a specialist on networks, I just like to program embedded systems
