Hello,

I have a pack of public ips.
I want some of them to be transparent in a sense that internal user could set public ip on his nic and it worked like setting on router.
Any suggestions?

I could, for example, to make ip pool of public ips and then add it to dhcp server, but dhcp already exists on local interface with internal ip addresses. I want only some pcs to be able to assign themself public ips (without using internal ones, no nat etc...). How to make public ip pool transparent or sthing like this? Or is it not possible without 3rd interface on router?

bump!

I would do that by bridging the public interface on the router with a VLAN on the LAN interface of the router. Then you can put the workstation in question on the VLAN and it use any of your public IP's (or at least those not used by the router itself). If you don't have a VLAN capable switch, then this won't work (or you just go get a VLAN capable switch and free yourself from the land of cheap switches).

You can also subnet your public IP addresses to allow some inside the LAN and then use Proxy-Arp on the WAN interface. This is a more complex setup compared to the VLAN method, IMHO.
