<P><FONT size=2>Why not load DHCP to bind to the second Ethernet port? You
can also use<BR>iptables to manipulate just the DHCP response packets (that's
what our DHCP<BR>appliance does).<BR><BR>Frank<BR><BR>-----Original

dhcp-users@isc.org<BR>Subject: Listening IP<BR><BR>Hi, I have four DHCP servers,
ISC DHCP 4.0.0 running on Solaris 10 x86 on<BR>Sun X4200 hardware.<BR><BR>These
machines have 4 network cards. The one I am using has id e1000g3.<BR><BR>On this
card there are two IPs, an
example:<BR><BR>e1000g3:
192.168.31.100
primary-name<BR>e1000g3:1
192.168.31.10 dhcp<BR><BR>My config file says to listen on the 31
subnet thus:<BR><BR>subnet 192.168.31.0 netmask 255.255.255.0 {<BR> option
subnet-mask 255.255.255.0 ;<BR> option routers 192.168.31.1 ;<BR>
option domain-name-servers 192.168.120.100, 192.168.120.101
;<BR>}<BR><BR>Problem is clients report that the DHCP server that gave them an
IP was<BR>192.168.31.100, the primary-name.<BR><BR>I would like them to think it
was the 192.168.31.10 IP, the dhcp name<BR>instead.<BR><BR>With other daemons,
like DNS, RADIUS, I am used to binding the service to an<BR>IP, with DHCP it
looks like you bind to an entire subnet, can this be<BR>changed? I would only
like the servers to listen on the "dhcp" interface and<BR>only reply from
it.<BR><BR>Thanks.<BR><BR>---------------<BR>Barry Dean<BR>Networks
