I manage two separate physical windows networks. I would like to allow access from one of the networks to the other as securely as possible. I am confident that the security within the respective networks is properly configured.
I want to allow access for two things specifically: exchange and server monitoring (snmp). Network "A" has exchange and the snmp monitoring software. For network "B" to get exchange, they need to go outside of the network through internet to get email. For monitoring, I currently have no way to monitor severs on Network "B", mostly due to licensing restrictions/budgeting.
The physical networks terminate in the same physical space with separate equipment. I have a Sonicwall NSA 2400 on network "A". My thought is to create an interface for network "B" on the sonicwall and NAT network "B" to network "A". This is a very simplistic overview. I would like to figure out if this would be a good way of connecting the two networks.
