Hi,
I have a problem to solve.  I have a dhcpd server and now I need a
dhcprelay on the same server.

ifconfig :
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8<VLAN_MTU>
        ether 00:08:02:f0:25:81
        media: Ethernet 100baseTX <full-duplex>
        status: active
vlan39: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 00:08:02:f0:25:81
        inet 10.1.1.254 netmask 0xffffff00 broadcast 10.1.1.255
        media: Ethernet 100baseTX <full-duplex>
        status: active
        vlan: 39 parent interface: fxp1
vlan667: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 00:08:02:f0:25:81
        inet 10.97.7.18 netmask 0xfffffffc broadcast 10.97.7.19
        media: Ethernet 100baseTX <full-duplex>
        status: active
        vlan: 667 parent interface: fxp1


Dhcpd in vlan39 interface. I binded Dhcpd in vlan39 to
add to dhcpd.conf file:
       local-address 10.1.1.254;

Dhcrelay in vlan667 interface.
grep dhcrelay /etc/rc.conf  :
 dhcrelay_enable="YES"
 dhcrelay_servers="10.97.5.2"         # dhcrelay server(s)
 dhcrelay_ifaces="vlan667"  

 Dhcpd works fine.
 
When I try to run dhcrelay :
/usr/local/etc/rc.d/isc-dhcrelay start
Starting dhcrelay.

Sending on   BPF/vlan667/00:08:02:f0:25:81
Sending on   Socket/fallback

Dhcrelay starts. But  sockstat tells me:

root     dhcrelay   69409 4  udp4   *:67                  *:*
dhcpd    dhcpd      68725 5  udp4   10.1.1.254:67     *:*

Dhcpd binded in address 10.1.1.254
But dhcrelay not binded in interface vlan667. How can I do it - to
bind dhcrelay in address 10.97.7.18 only?
I try http://marc.info/?l=dhcp-server&m=113219435513941&w=2, but
unsuccessful.

Thanks.
