Ok heres what i want to do:-

router has wan ip of X.X.X.209 sending dhcp to lan port 1 devices in the dhcp range 192.168.0.100-200

AND supports a device with its public ip set to X.X.X.210 on lan port 2 effectively routing all traffic destined for X.X.X.210 to lan port 2

Can this be done and no DMZ port forwarding etc is not an option device NEEDS to basically be an un-firewalled public ip address device on the internet! And yes i have 5 public ip's available to me.

I have a VBX2000N-K and a V2862AC-K that i need to do this on but the setup should be same if it can be done!

Thanks all
