Joining two networks
-
My N+ skills and knowledge is a little wanting. Let's say I have two networks, A & B, each with it's own Windows 2003 Server, it's own Domain, it's own ADSL connection and hardware firewall. Network A's Range is 192.196.1.xxx Network B's Range is 192.196.0.xxx I had an optical fibre connection installed between the two networks. Now I want A to be able to use the resources on B (Eg. Printers, Databases, Internet etc.) and vice versa. One way is to change the IP range of A to be in the same range as B, but is that neccesary? Changing the range will have many other implications. Can't I setup a normal network over 2 ranges using the subnet mask somehow?

"Watching Migthy Joe Young made me hate my life..................................I want a gorilla!" A. HavemannDo you work for EDF Energy? If not, you should change those IP addresses: the class C private addresses are 192.168.0.0 - 192.168.255.255. You need a router. You also need some way to make computer browsing work over the link, and for this you need - I believe, still in the Active Directory domain era - a WINS server, and to configure your workstations and servers to use this WINS server. Traditional Windows computer browsing works via broadcasts, but these broadcasts are not routable.

he is allowed to use any network address range, even if classes A, B and C mean something particuliar. BTW, you're wrong in saying Class C goes from 192.168.0.0 to 192.168.255.255. Class C only means that the network mask is 255.255.255.0 (so, machines from 192.168.0.1 to 192.168.0.254)

"Watching Migthy Joe Young made me hate my life..................................I want a gorilla!" A. HavemannYou need two routers Network A ----> Router A <---- Fiber Link ----->Router B <--- Network B On the network A, you configure the internal IP of Router A as the gateway for Network B. On network B, use internal IP address of Router B as the gateway for Network A. If you don't want to use a bridge or router, you have to change the IP addresses to the same subnet.

You're right, I use 192.168.xxx.xxx Anyway, it seems there is no simple solution, I'll read up on the WINS server, thanks.

Mike is right, the ip addresses given in the original post are public ip addresses, and these are not to be used in LAN/private networks.

I think he meant the private IP range, not class C. He is assuming that the person intended to use a private IP range, and mistakenly used a public IP address. In that sense, the tip to use 192.168.x.x may not be a bad one. It may help the guy, if he is indeed trying to use a private IP. Thomas

i worked on a network prior to the serious uptake of the internet that used 130.xxx.xxx.xxx IP addresses, which was great until we got firewalls etc when Reverse DNS lookups started to return the domain of a uni in Australia for Internal machines. It was very confusing at first.
