Hi Win,
I've found a better answer for this scenario. You can use local proxy arp on
the ethernet interface of the router.
Int fa0/0
Ip local-proxy-arp
Cheers,
Huan

Hi,
Forget to add that you can't use HSRP,VRRP,GLBP,.... I didn't think
about the secondary address because I was convinced that you can only
configure a secondary address for a different subnet.
It seems to the massive reactions that this is the way to go , I'm going
to test it today
Thx
wim

Hi Wim,
I assume that 192.168.1.254 does not exist on your network, but the DHCP
server is wrongly configured to point all work stations default gateway
to that IP? If so, you can use secondary address of 192.168.1.254 on
your router, in addition to the primary IP 192.168.1.3.
interface FastEthernet0/0
ip address 192.168.1.254 255.255.255.0 secondary ip address
192.168.1.3 255.255.255.0
You can also configure HSRP, VRRP, with 192.168.1.254 as the virtual IP
(you do not need any other router as standby).
Please let me know if you find a better solution.
Cheers,
Huan

Hi,
In one the labs of internetwork expert you have the following question
Suppose a consultant configures a DHCP server and misconfigures the
default gateway ( ex 192.168.1.254 ) . Configure your router with IP
address
192.168.1.3 to answer on ARP requests for 192.168.1.254 .
I first thought to configure proxy-arp but this is for different
subnets, does anybody have an idea ?

Wim
