How access two networks using a USR 9105 adsl modem-router?

Hi.

I want to access two networks using one adsl modem-router (USRobotics 9105).
Currently I have the following schema:

Dlink 900+ AP: IP: 10.11.12.12 Subnet mask 255.255.255.192. Gateway: 10.11.12.1

USR 9105. IP: 192.168.1.1 subnet mask 255.255.255.0. 2nd IP: 10.11.12.13 Subnet Mask 255.255.255.192

PC1: IP: 192.168.1.2 subnet mask 255.255.255.0

PC2: IP: 192.168.1.5 subnet mask 255.255.255.0, 2nd IP: 10.11.12.14 subnet mask 255.255.255.192

PC3: IP 10.11.12.15 subnet mask 255.255.255.192

I have given “add route 10.0.0.0 255.0.0.0 10.11.12.12” in command line of USRobotics and my network works as follows:

PC1 can access the internet through the DSL
PC2 can access both internet and the Dlink AP.
PC3 can access only the Dlink AP.

My goal is to remove from all the PCs the 10.xx.xx.xx IPs and replace them with 192.168.1.xx and still be able to access the Dlink through the IP 10.11.12.12.
Is that possible?
I have been told to use a proxy but that needs to have a pc always on serving as proxy. And this is not a choice in my case.
I have found this http://www.usr.com/support/9105/9105-fi ... rence.html but I cannot understand much of it…
Please note that I am an amateur and this network is at my home using it just for fun.

Thanks in advance,

Hi - welcome to Routertech

Can you explain a bit more about your setup and what you are eventually trying to achieve ?

Are you basically linking a wireless AP to a non-wireless adsl router to allow wired and wireless connections at home ? and if so can all PC's connect to the AP via wireless - if so then this would presumeably resolve your problem in one manner ?

Hi. thanks for the welcome and for the quick reply.

The AP connects in client mode to a wireless network. And I connect the Dlink with my 9105 through a wire (utp). The adsl router also (of course) connects to the internet. What I want to do is to be able to access both internet and wireless network from my PCs but I want to have them IPs of the local network (192.168.1.xx) since I will be able to keep max of 2 IPs from the wireless network (10.11.12.xx).
Any ideas?

Can you do a simple diagram in Paint? I'm lost.

My goal is to make PC1 access both wireless and internet network. Currently is able to access only internet.
PC2 can access both.
PC3 can access only wireless

thanks once more for your time

Right then.

I'm not sure what options are available on the DLink as I have not read the manual in detail, however on most routers it is certainly possible to restrict access for a given LAN address to the Internet through the Firewall packet filter. This could be used to allow access for PC 3 to the wireless network only.
From your diagram (for PC 2) I am not aware of any way to have multiple IP addresses (subnets) on the same network card without the use of something like VMware on the PC. You could in theory fit two cards of course ......

Why do you want different address ranges? This should be possible with the just one, or am I missing something?

Hi there again.

Yes, PC2 is something like VMWARE

I need to use different address ranges because I will be able to keep a max of 2 addresses of the wireless network. Also using a different IP range will give me some protection since wireless network I connect to is an open one.
I will check out with Dlink if it is blocking access from different IP range.
Thanks for pointing that, I will let you know any way...
