Is there a way to redirect all traffic going to an IP to another IP on the same subnet?
I need to decommission a DNS server. 192.168.1.4, and unfortunately I can't reuse the IP on any of the other existing DNS servers, nor I can create a new VM (to assign this IP) due to licensing issues. What I would like to do is, use this .4 IP on any other network device, and configure the device to forward that traffic from .4 to 192.168.1.42
Pretty much this client doesn't want to spend $ on new hardware. So can't buy a new license for the vm, nor a new baremetal server, nor new layer 3 switch. I can only play with what they have already which is Cisco routers, ASA's, layer 2 switches, Hyper-V server.
obviously, I know that the purpose of routing is to connect different networks. However, this is a special circumstance, so I'm looking for a workaround, or use of NAT or bridging or anything else that you might have used in the past to solve something like this.
