I have enbabled IP Routing on my multihomed Vista Desktop, but unable
to get it to work.
I am unable to connect from 192.168.5.3 (XP Laptop) to 192.168.1.6
(Vista Desktop #2)
Connect, as in ping, RDP, etc.

Following make my network.
192.168.5.1 (Netgear router #1 connected to internet via ISP #1)
192.168.5.3 (XP Laptop)
192.168.5.5 (Vista Desktop #1, multihomed) wired connection
192.168.1.10 (Vista Desktop #1, multihomed) wireless connection
192.168.1.1 (Netgear router #2 connected to internet via ISP #2)
192.168.1.5 (Vista Desktop #2) wired connection
On Netgear #1, added static route to 192.168.1.0 via 192.168.5.5
Firewall disabled on Vista and XP Laptop/Desktops

My Vista Ultimate desktop #1 connects to two networks
a) 192.168.5.0 (wired) through interface 192.168.5.5
b) 192.168.1.0 (wireless) through interface 192.168.1.10

I enabled IP Routing by updating the registry key below on Vista
Desktop #1
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip
\Parameters
subkey : "IPEnableRouter" entry to 1
and rebooted

C:\Users\Benoy George>ipconfig /all

From the routing table, you can't access the 192.168.1.x because every traffic goes to the router 192.168.5.1. Post back with the result of ipconfig may help.

Man what you have here is really confusing. You need a visio or something to
get this point across. Besides it doesn't look like you have it configured
properly from what I have read.

First, you can only have one default gateway on a computer. Your Default
Gateway should be the one that connects you to the internet. I am assuming
that is you 192.168.5.0 network. Therfore your default gateway should be
192.168.5.1.

Now on a computer that is not multihomed that you want to allow to connect
to you 192.168.1.0 network you neet to tell your computer how to get there.
It is not accessible from the default gateway so you need to tell it it's
next hop. So that would be the Multihomed vista box you have enabled routing
on. So assuming Vista #1 that address is 192.168.5.5. So on you xp laptop
you need to:
route -p add 192.168.1.0 mask 255.255.255.0 192.168.5.5
*as a side note you'd have to do this with eleviated priv's on vista

I wouldn't use the routing feature of your switch. However I think it is
not working becuase your switch doesn't know where 192.168.5.5 is. You'd
have to change that to route through the interface ip of the machine that is
connected to it.

Hope this helps.
 
We have a few issues in the configuration.

1. IP Address. . . . . . . . . . . . : 192.168.5.3
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.5.1
The 192.168.5.3 and 192.168.5.1 are not in the same subnet.

2. IPConfig Result from multihomed Vista Desktop should not assign two default gateways. Otherwise the multihomed computer may be confused and no route return.

1.
I am not sure why you mentioned that 192.168.5.3 and 192.168.5.1 are
not in the same subnet.
The subnet mask is the same 255.255.255.0 and both belongs to
192.168.5.0 network.

2.
I had both interfaces enabled for DHCP, and thus it got a seperate
default gateway per interface,
I have changed this to static IP and thus have the following in my
multihomed PC

Nothing personal, but pehaps you'd be better off just getting a router that
can do what you are trying to accomplish.

THe Netgear FVS124G cand handle dual wan connections.
http://www.netgear.com/Products/VPNandSSL/WiredVPNFirewallRouters/FVS124G.aspx

What you are trying to do is complicated. I think you want a High
Availibility Internet connection? Right?l

The above stated router will load balance between the 2 connections where
Windows saturate one then "Maybe" use the other. If you don't want to get a
new router then you would be better off installing a 3rd nic in your
MultiHomed Vista box for a 3rd network and use that computer in place of the
2 Netgear Routers.

If I were you I'd get a new router, as this is what routers are made for.
Vista wasn't made for this, but we may be able to configure it to do it with
some work. However you would need to change your network topology. Is there
a purpose to it being configured the way it is?
