Using VPN to maintain a flat network?
Posted on 2010-09-15
We currently have a completely flat network with only one location. We are on the 10.10.0.0 /16 network.
We are now in the process of opening a co location(location #2) that is connected to main office via a private circuit. We originally thought the connection to the co location was a layer 2 connection so we IP addressed all of our new servers and devices within the 10.10.0.0 /16 network. We recently just found out the connection to the co location is a layer 3 connection.
We are now presented with a problem. We can re ip the co location servers and devices. However, this will take quite a bit of time, testing, and man power. We are trying to avoid this if possible.
The other option we are looking at is using some type of VPN to establish a flat network between the main office and the co location. We will already have layer 3 firewalls in place that could provide a VPN service. Is is possible to maintain a flat network in these circumstances.? I looked at site to site VPNs but it seems they are more geared for connections over the public internet; the two connecting networks appear to have to be on different networks. Any ideas on how to keep the main office and co location a flat network so we do not have to re ip address all the equipment going to the new co location? Or should we go ahead and just re ip.
Thank for your help. it is appreciated.
