Two Different IP Ranges on One Network

I need a little bit of guidance regarding a request that one of my clients is making. We have a WAN that consists of two different LANS. The one IP ranges is something like 88.888.88.x and the other is 77.777.77.x. We are trying to add a device to the 88.888.88.x network with an 77.777.77.x IP address associated with it. We have struggled to get the 77.77.77.x IP address to route. Does anyone have any suggestions? Any help would be greatly appreciated! Thanks.

Thanks for the quick reply. I just made those IP addresses up. I didn't do a very good job!

Let me start over. What we are trying to do is get a video conferencing camera going. The video conferencing camera needs to have a certain IP address in order for the other sites within the WAN to communicate with it. The camera will reside on one LAN that has an IP range of X, but the IP address associated with the camera has an IP range of Y. We are not sure how to get the LAN to recognize the Y IP address. Let me know if this still doesn't make sense. Thanks.

 

The LAN right now is 173.26.200.x and the camera is 74.19.183.162. The camera is a Polycom.

 

Why are you using public IP ranges for your network? This is almost always a really bad idea. It would be MUCH smarter to use one of the IANA reserved address ranges for private networks.

192.168.0.0 --- 192.168.255.255
172.16.0.0 --- 172.31.255.255
10.0.0.0 --- 10.255.255.255

 

We do use private, again I just made those up. So I will quit doing that because I am creating confusion. Let's take the scenario you provided and go from there. Thanks for you patience John.

 

So you want a camera on to live on network "A" but talk back to applications or servers on network "b" correct? If you have a WAN i am sre you have some routing devices in place between the networks. You should be able to give the camera a IP for network it lives on, if your routing and ACL's are correct you shuld be able to hit it from ether side of the router.

Why dont you detail your network alittle more for us. Does it span over diffrent geographical locations? Is it all in the same building? is your "WAN" going over a point to point link? or VPN?

 

Yes. The camera needs to be on the 173 network.

(My next thread will have the real IP's)

 

Memnoch,

The WAN does span over multiple geographic locations and it is a point to point link.

 

Okay, I just re-read the thread. You really need to post your network configuration so we can figure out what you got going on.

 

What kind of routers are you using? Cisco?

 

This is how it currently is setup. Any suggestions on how I could it different or why you don't think it would work, would be appreciated. Thanks again for all your help.

 

Your gateway device, is that a sonicwall? It seems like you have your LAN and then you have a DMZ. I dont really see what is happening here.
