2 dhcp servers 1 network.

So i have 2 dhcp servers on my network (router and pxe server).
Router for actual network and server runs dhcp for pxe server.

Router 1:
Just setup normally
Internet comes in on 1 nic and goes out to switch on another nic.

Server 2 and all other computers are connected into this switch.
Server 2:
Server 2 only has 1 nic.

Code:

default-lease-time 86400;
max-lease-time 604800;

authoritative;

subnet 192.168.0.0 netmask 255.255.255.0 {
        range 192.168.0.10 192.168.0.49;
        option subnet-mask 255.255.255.0;
        option broadcast-address 192.168.0.255;
        option routers 192.168.0.1;
        filename "pxelinux.0";
        next-server 192.168.0.130;
}
"""

now i plug my laptop into switch and its picking up on the pxe servers ip list. Would prefer if this was not the case.

Anyone know what i can do?

Thanks

You can lock the PXE down to supply leases only to machines
with certain MAC addresses.

Another approach might be to force the client to talk to
a specific server, but that depends on the client software
you're using.

is there no way to lock down pxe server only to lease to pxe requests?

Looks like there might be, I've never had to try to set it
up like that myself, but did find a few references on google
that suggest it can be done ...

looks quite promising.
