I have two computers that I want networked wirelessly together.
Computer A has an ethernet connection with a static ip of 172.1.116.x
and a wireless adapter that gets a dynamic ip of 192.168.2.xxx from the
wireless router. Computer B has an ethernet connection that is hooked
directly to the wireless router and also gets a dynamic ip
(192.168.2.xxx) from the router as well.
I need computer B to see computer A's static (maunally assigned) lan of
172.1.116.x through the wireless connection of 192.168.2.xxx I also
should probably assign an alternate static ip of 172.1.116.x to
computer B's ethernet connection. I cannot change computer A's lan
static ip because it is used to control a whole feed mill. I also need
the 192.168.2.xxx wireless netowrk between the two so both can access
the internet coming from the router
How should I go about networking the 2 computer's 2 network connections
together? I don't know if a bridge will work. Basically, I need both
computers to see each other's static lan of 172.1.116.x through the
dynamic (DHCP) wireless connection of 192.168.2.xxx.
My router won't let me assign it an ip of 172.1.116.xxx nor use an ip
range 172.1.116.x to 172.1.116.xxx with the DHCP server.
Any help would be appreciated. Thank you very much.
Do you really need two different subnets and two different networks?
If you configure the wireless router to assign addresses in the
172.1.116.x range, would everything work?
I don't think that a network bridge can do what you want. Its
purpose is to combine multiple physical networks into a single logical
network with a single subnet. I've written a web page with details:
XP ICS - Network Bridge
http://www.practicallynetworked.com/sharing/xp_ics/networkbridge.htm
To route traffic between the two networks, enable TCP/IP forwarding on
Computer A, as described here:
How to Enable TCP/IP Forwarding in Windows XP

You'll need to assign a static 192.168.2.xxx address to Computer A's
wireless connection and use that address to define a static route on
computer B. For example, if computer A's wireless connection is
192.168.2.10, define this route on B:
route add 172.1.116.0 mask 255.255.255.0 192.168.2.10
Computer B will then have access to the 172.1.116.x computers using
their IP addresses. Accessing them by their computer names will
require an Lmhosts file on Computer B that maps the computer names to
IP addresses.
