Here is my situation and this doesnt seem possible without having to re-address several things.
I have addressed a new network which is going to be hosted at a remote location these are the networks below that exist at that site
10.10.10.0/24
10.20.5.0/24
10.10.20.0/24
10.10.200.0/24
My local network here has different addressing (was set up proior)
100.100.50.0/24
100.100.60.0/24
100.100.20.0/24
For all practical purposes this works fine however I was recently tasked to move some of the remote network here and have some of the remote network at the remote location during the migration (the logic which i think is not practicle I dont want any downtime while we transition this new network to remote location) So...here is the issues I have been running into. I chose /24's because it allowed for future growth and its easy to route these networks what I have is a Virtual Environment that uses a SAN.
Question: How can I allow some from 10.20.5.10/24, 10.20.5.30/24 or 10.10.200.20/ on my local network and still have the same addresses and GW's the other site and allow the servers to talk?
Network 1
10.10.10.1/24 ------> GW 10.10.10.254
10.10.20.1/24--------> GW 10.10.20.254
10.20.5.1/24----------> GW 10.20.5.254
Network 2
100.100.50.1/24 -----> GW 100.100.50.2
I have added Vlans on one of the switches on the local network to accomodate the remote networks IP's eg 10.10.20.3 eg.. I think the only way this is going to work is to create a routed port on the Switch > connect to firewall and add the static routes from the firewall pointing to the routed interface on the switch. This is the only thing I have yet to try.
