Unfortunately I cannot change the destination IP address, and I do need them all to communicate with the same device. PBR won't work (if I understand correctly) because it would just route all of the traffic to a different IP address, yielding the same issue. I tried using VLANs, but that doesn't fix the issue since there will still be conflicts on the host machine. If I purchased something with NAT support, would it be possible to setup a NAT on a per interface basis that would translate the destination IP addresses to different IPs (ideally still inside the network, but outside might work as well)? Something else to note is that the source IP addresses are unique for the data that I am trying to receive. I was able to make a python script on the machine that filtered out information based on source IP and then sent it over different ports, but it was, predictably, far too slow. I will checkout L2NAT and see if there's anything useful there. Thanks for the suggestions.

Hello, I have Cisco Catalyst 3560 network switch and am trying to receive UDP packets from four attached devices. Each device is sending packets to the same ip address and port, and this destination address cannot be changed. Is it possible to redirect which ip address or port the devices reach using the switch so that the traffic can be distinguished? Ideally I would say all traffic on ethernet port 1 goes to a certain ip address and port, and all traffic ethernet port 2 goes to another, etc. Thanks,
