We will soon be moving some servers over to a datacentre, and i am trying to figure out how we will route between the two locations. Here is a description of what we will need to do:
Office Cisco ASA5520 Cisco ASA5520Datacentre
Office subnet: 10.10.10.0/24
Office ASA: 1 Datacentre ASA: 2
the line between the 2 ASA's is a 'private' fibre connection.
ASA1 LAN ip is 10.10.10.1 ASA1 fibre ip is 10.10.20.1 ASA2 fibre ip is 10.10.20.2 ASA2 LAN ip is open
I have three questions:1) Can I run the 10.10.10.0/24 subnet in the datacentre? If so, how does this compare (efficiency, security, convenience) with choosing a different subnet. Choosing a different subnet is not that big a deal considering what we're doing, but not having to do so would save us from having to change a whole bunch of server ip addresses over.
2) How do I go about configuring the routing between the two ASA's to allow the traffic to flow in both directions unrestricted? Only unicast traffic is necessary.3) If NAT is necessary, what type of NAT (or PAT) should I be using?
Thanks in advance.
