I have a PC that has 2 NICs in it its connectected to a 10.x.x.x/24 and a 192.168.x.x.
The 10.x.x.x is grabbed via DCHP from the PIX the 192.168.x.x is statically nailed w/ a default route and I want my 192.168.x.x to be the default route.
However when the machine gets the DHCP 10.x.x.x address from the PIX it has a default route incuded as well and the machine (Windows 2000) get very confused.
What I want is the ability to have the PIX not advertize a default gateway in DHCP as this interface on the PIX is a stub network and I dont want it routing anywhere off network. That interface simply does a bunch of static NATing for me.
The one thing the documentation at cisco is not clear on is whether doing a 'no dhcpd option 3' will actually work - it doesn't show up in the running config - the no command probably only clears the line if it's set in the configuration, I don't think it will turn off sending of a default route.
You may have to do a workaround - actually specify the 192.168.xxx.xxx to be the default route that the pix gives when it replies to the dhcp request - try
dhcpd option 3 ip 192.168.xxx.xxx
And that should resolve your issue, assuming that the 'no dhcpd option 3' doesn't work.
