A quick overview of my environment:
- One gateway/DHCP server connected to multiple ISPs and connected to the switch
- One Netgear GS748T 48 port switch (and a few trunked switches for the same subnet)
- No gateway right now (don't have any spare devices with more than one NIC)
- one DHCP server
- One netgear GS748T
Network B is a testing environment. There is nothing connecting the two networks right now. I still need internet connectivity so I wanted to just connect network A to B somehow and have no conflicts between the two with DHCP. I know how to do this by setting up a gateway on network B and using it's second interface to connect to the gateway on network A, but I don't have any devices with two NICs to allow that. I was hoping I could just drop a line between the two and do some settings that would keep their clients from getting confused as to which subnet their in. Any guidance on how to get internet to network B without any conflicts? I assume it's easy, I know protocols pretty well, I'm weak on networking hardware as I'm a programmer.
Update: Forgot to emphasize that these networks should be completely separated. The connection between the two only provides internet access to network B.
