Multiple IPs on 1 NIC-How do I forse them to use the same gateway?
Hi there!
I would really appreciate some help using Windows 7 to route some IPs.
I need to use and move a wireless device, that is a part of a larger system, from one area of a large establishment to another and back again using two different networks. The device has a static IP of xxx.xxx.200.119. This address can't change or be dynamically assigned.
In the main area of a large building the device has to communicate with IPs xxx.xxx.200.100 to xxx.xxx.100.118. This is the only wireless device and it connects to the other IPs through an access point, that's not a router, with a wired IP of xxx.xxx.200.113 and the SSID is Room1. The subnet mask is 255.255.255.0 and the gateway is xxx.xxx.200.1.
The device can and will be re-registered, using a docking station, to operate in a completely different area of the building. In the second area it has to communicate with IPs xxx.xxx.200.119, .120 and .121. Here the access point has a wired IP of xxx.xxx.200.120 and SSID of Room2, again it is not a router. When the device is re-registered only the SSID of the access point, to which it needs to connect, is changed.
xxx.xxx.200.119 is a laptop which is connected to the second AP with IP of .120 . All of the above functionality is configured and works fine but here is my problem...
In the second area of the building the IP address that the IT dept has given me is xxx.xxx.242.211. Subnet mask is still 255.255.255.0 and the gateway is, you guessed it, xxx.xxx.242.1. So I figured no problem I'll just assign both the xxx.xxx.200.119 and xxx.xxx.242.211 to the NIC in the laptop. But this does not work because the laptop then thinks that the IP's xxx.xxx.200.100 to .118 are local and therefore does not use a gateway so I loose communication with them. Therefore, what I think I need to do is find a way to route those IP's through the .242.1 gateway.
Sorry for the long winded description!!! Many thanks in advance for any help given!!!
