Looking to see if this is possible without re configuring all the IP address for 100+ servers.

We have two separate Networking infrastructures that do not communicate currently. We are in the process in setting up a VPN connection between the two that will allow a new security software to monitor the Infrastructure on one side. We also running out of room to include more servers on one of the infrastructures, and we have a new host on the other infrastructure with a lot of room on it. Our boss wants us to look into taking current SharePoint environments and moving them over the other network infrastructure and have them communicate back over the VPN for their public IPs. This way they still look like they are coming from their original source.

I'm looking to see if this is possible, viable, or even a good idea. Any advice would be helpful (if that is clear as mud just ask me to clarify any information).

Is there anything stopping you from updating the DNS records and have the records reference the new IP addresses in the new infrastructure without tunneling through the VPN?

Technically what you have described will work, there is a possibility that users will see a decrease in performance when accessing SharePoint depending on the performance of the VPN.

the only thing potentially stopping us is our boss.

My main concerns are re-assigning new IPs to 100+ servers, which in our environment is about 2-3 IPs a server. If the VPN connection goes down then so does our client's servers and sites. the performance is also another concern.

The other options i gave him was to bring the other infrastructure under our main network, or physically move the host to the other network (they are actually only a few racks apart).

you can move the entire farm and keep the IP configuration if in the old location you can segment your LAN

You can configure routing between main site and the new one, on borders routers. If IPs overmatches , you will use NAT in main site
But keep in mind that the new traffic to SP will go trough that VPN connexion which will be smaller that your LAN infrastructure

. Depending on your organization structure of users and tasks users satisfaction could go down :(
