HP MSR router, configure multiple IP's on WAN interface
The router is connected in the datacenter on a Switch.
We received 10 public IP's in the same subnet.
We want to nat some public IP's to local subnet example 192.168.1.0/24
We want to use the public ip's direct on the servers without nat.

How can we configure this?
Do i need to work with subinterface's on the wan0/0

Typically for this purpose you get another IP address range (/30) from your provider and configure that IP address on WAN interface. And use other range for NAT pool and servers.

Other option would be to subnet your IP address range.
One part can be assigned to NAT pool and WAN, other can be assigned to servers.
example ISP address on ISP router is 1.1.1.10/28. In that case you can configure 1.1.1.10/30 on your WAN interface and you can use 1.1.1.0/29 for servers. So assign inside interface ip address from that range. The problem with this is that you loose at least 2 IP addresses (1.1.1.7 & 1.1.1.8 - 3 addresses if you count IP address assigned to interface that will be used as default gateway for servers).
Do i need to work with subinterface's on the wan0/0
No, you don't. ISP will configure route(s) to send you traffic that have destination IP address assigned to your company. How you will manage it - it is your problem. :)

PS
Maybe it is possible to use unnumbered interface for this (to save IP addresses), but I didn't ever use in such fashion.
