Just wondered what people thought about the idea of a test network being used in a company.
We have such a beast, however, I am just wanting to clarify some things which I am not 100% comfortable with, and just wanted to know am I being very old fashioned, or is there some basis to it?
We currently have a core switch with several Vlans on it for internal purposes. The people who configured this put an extra Vlan for the test network, currently all traffic can pass through, but it will be locked down using ACLs on the core switch. The reason for this apparently is so we can use the Vlan capabilities on the internal switch to assign ports to the test network.
Is this really a separate network from the "live" environment, could there be any problems?
The other thing is, we have a small ADSL connection to simulate WAN access, however, for some reason, we have had a few of our existing public IP addresses (on the live system) set aside for the test network, going through our existing Pix through to the test network. The reason for this is that the ADSL connection will act as a loop through so we can do external tests. I have tested this and it works, but I was thinking we would be able to use a set of public IP addresses (or even just one address on the DSL interface), and use them/it as our external address if required?
I realise I have only scratched the surface, but I just wondered what sort of problems we may come into with this type of setup (if of course there are any)?
