Connecting 2 lans (two different ADs)- 2 routers (2 different ISPs) - 1 DHCP (for all non-manual settings)
Posted on 2014-09-30
I have two small law offices. Currently they are on different IP ranges ("A" is 192.158.2... "B" is 192.168.1...) I am replacing the old SBS2003 on "B" with Server 2012R2 and "A" is already on SERVER 2008R2 with AD, DNS, DHCP. We had to separate them because originally they were both running SBS2003. They both have their own internet service.
1. The 2008 Server is running DHCP and all new devices, phones, tablets, etc,,, connect via that internet and network
2. The two offices share two high end MFPs and one of the things we are trying to do is to marry them together so they can both use all the features of these devices. We currently have both MFPs hardwired onto the "A" switch and on their network segment, the other office has stuff "emailed" from the scanners to their accounts, They ("B") cannot print to these devices.
What I would like to do is the following:
Have both Networks on the same IP range to allow them to use the MFPs and it is OK if the DHCP for additional devices are provided by the current (A) server. ("A") has 7 PCs and Server. "B" will have 1 SERVER and 4 workstations. I can manually add all the PCs onto different sections of the same IP range ("A" will be 192.168.2.1-75, "B" could be 192.168.2.150-175) The two Servers will be within the scope of THEIR network.
My concerns: As both will be running AD, I assume that each office will be using their servers IP as their default DNS, which in turn will route the traffic through that offices router ("A" is 192.168.2.1 & "B" is 192.168.2.254) - will they interfere with one another (again, only 1 DHCP server)? Is this the best way to do this under the circumstances and using the existing switches and cabling? If I keep them on different IP ranges, is there an easy way to bridge them so both offices can use the MFPs?
