Assign one of my public IP directry on customer server

[Jimboom]

Hi.

One of my customers asks me to have Public IP directly configured to is server networks card instead of One to One NAT with VIP.

For example :

I Have 206.x.x.34/28 subnet. on my WAN1. He asks for .39 direct on its servers.

How I can do this. I have Fortigate 81e.

If the ISP's GW device has one of the /28 IPs, any wacky attempt to split the /28 to /30s would probably fail. Because the GW expects packets directly from .39 without additional hop. But if you actually have another /30 subnet and ISP can swap the GW IP to one of them, then you can use another one in /30 for WAN1, and assign /28 to FGT's LAN side interface. Or get another subnet for servers conversely.

If the customer insists their servers need to have real public IP on them, that's the way I see as workable options. But I don't see any reason they have to have real public IP.

Thanks for your response. For now I can't split my scope. But, it is possible to ask my isp a bunch on IP to use for your scenario.

Now, is the customer really needs WAN IP on servers network card? I'm not so sure. But I don't have the argument to say NO!

The need is for a deployment for IP Voice system, Mitel MiBusiness Express with MiBorder Gateway.

Those two Virtual Machine will be deployed on my datacenter. The engineer assigned to this deployment asked me for a public IP assigned to the second NIC of the Border Gateway.

If it's a datacenter situation, I would just order another subnet for customer servers, and wouldn't share the outside subnet for the FGT you manage.
