Aloha,

I want to add a dhcp NetGear WPN824v3 wireless leg for 2 laptops (1 MS7
and 1 Ubuntu Linux) on my existing static IP lan of 10 desktops and
servers (all FreeBSD).
I run fixed IP on both segments now using 192.168.1.x addresses but
would like to have dhcp segment on the wireless side since the laptops
have to be reconfigured every time they come back on my home/office lan.

Has anyone on our list had experience with this or knows of a how-to?

Thanks,

It is trivial. Configure the wireless DHCP to assign a pool
of addresses in the 192.168.1.xxx that you are not using.
For example 192.168.1.192-224 for 32 addresses. Use a netmask
of 255.255.255.0 and they will all talk to each other.

I assume you already having something else doing the NAT to
get to the internet, so turn off NAT on the wireless router.
Set the default route to the main gateway that does nat on
your current LAN.

Aloha Dave,

Thanks for the info. From searching and reading I thought it was not as
complex as some people told me. Indeed the Netgear is just a point on an
existing lan and I have NAT on a Linux router/firewall.

I'll try setting this on the NetGear wireless once I get back at the
office.
