Seperating Networks

By abramenkosam ·
I have a strange situation here. A new client has asked me to help seperate there networs for them but at the same time allow for sharing of a few resources. (Printers, drives, ect.) To start the network is setup as follows. Have a T1 coming in to a 4 port swtich. From there there is a 2 cables, one to router1 and another cable to router2. From router 1 we have a cable to DC1 running 2003 server. And another cable to 2 24 port switch. On router2, there is only a cable going to another dc2 for a totally seperate domain. No switch there at all. Now everyone in the building is connected to the switchs and set on router1 for internet and network shareing ect. Their previous IT dept told them it was impossible to have two networks working together at the same time. So instead of setting up dc2 for sharing of drives they put share point on dc2, and set everyone up to go out throught the internet and then back in to hit the sharepoint. My job is to seperate the two networks but still be able to have a little sharing between the two. My idea was to plug router1 into 24 port switch1 and router2 into 24 port switch2. But then how would I solve the problem of setting up sharing between the two?

What you have is really three networks

by Dumphrey In reply to Seperating Networks

network A on router 1, network B on router 2, and network 3 consisting of T1 csu, and the wan ports of router 1 and 2.
All you need to do is create acls to allow services from the other network ONLY to be allowed in to access ONLY the share.
Or depending on the routers, you could direct connect them with an Ethernet crossover, or serial etc, and create a forth network, just for allowing full access between the two networks (or limited by acls). This is a good solution because it does not congest your wan interface at all.

Really you should move this to questions instead of discussions, but that,s neither here nor there.
