- Any routers that allow mapping of MAC to DHCP
- Posted by amit das on June 28th, 2003
I am running XP, currently have a networkeverywhere(linksys) router.
The problem is that when power is lost to the router all the DHCP
clients are assigned different ips from before the loss of power. I am
guessing the first computer it sees is the one it gives the first ip
to.. and so on.
This causes a problem because I have port forwarding enabled and when
the router restarts after power loss there is no gaurantee the same
lan computer will get the same DHCP ip.
Is there a home router that will allow me to specify a DHCP address to
a MAC address this way the lan computer will always get the predefined
DHCP ip?

Netgear FR114P can do it.

I forgot to mention that I get a dynmically allocated
ip address from my cable provider... so is it still possible to
statically assign my lan pcs even when the main ip address, and dns
keep changing? I was told to
keep all my windows tcp/ip settings to "obtain
automatically"

You were told that by a cable provider who was assuming that you had a
computer connected directly to the modem -- or a tech who doesn't know
very much about how a LAN works. The WAN side of you router has to be set
up to get an IP from the cable system (sounds like it is). You can set up
the LAN side however you want. So yes, you can assign static local IP's to
your computers.

Ok. as I try to change my xp tcp/ip conf. from obtain auto. to fixed
ip, XP asks for a DNS server, it seems mandatory. after restart the
router now finds my fixed ip computer but the computer cannot connect
to the internet due to lack of dns settings. Does this mean I have to
set the DNS on each computer. Suppose my cable provider changes dns
servers on me.. does this mean I have to change each computers tcp/ip
settings... this is what I do not want to do!

Why not use static ip's at the pc level?

This is dependent on the router capabilities. I have an Addtron (no longer
in business) which can serve as a DNS proxy for the lan. With it, you
simply point DNS on the client machines to the router IP (same address as
the gateway). If the requested data is not found, the router proxy fetches
the info and caches it.

D-Link DI-713P Wireless Access Point / Router also supports MAC based DHCP
assignment.
By the way for those who suggest static IP address as a solution, consider
the case where a laptop needs to be used at different locations, and must
have different IP addresses. And the location authanticate a computer by a
specific MAC address.

Well, BOOTP which came before DHCP was designed to do that.
If you set a long, or infinite, lease time some DHCP servers will reassign
the same address. But then some won't.

If you're running Windows 2000 or XP, you can configure it to try dhcp
first, then default to a static IP. With Linux & OS/2, you can start up in
static, then switch to dhcp.

Lease time has nothing to do with retaining the same address. The normal
practice is to renew the same IP, as long as possible. Some ISPs don't.
