You don't normally do it the way you're asking on Checkpoint. 
Instead you normally setup the additional ip address in the NAT field of the object you want to NAT to and set it up as a static NAT address.

larstr is indeed correct here bud.

Although you can assign more than 1 IP to an interface and Check Point will detect it, it is normally done through the assignment of NAT.

To be clear on this, can you tell us what you want the extra IP to be used for?

Hi deimark and larstr,

the extra ip is for our additional web server. will be assigning a static nat.

"the additional ip address in the NAT field of the object you want to NAT to and set it up as a static NAT address"......can you please elaborate, OR do you mean.. create a new node object (in my case, a new host) and enter the necessary details such as IP addresses (host's internal ip and static Nat ip)

"Although you can assign more than 1 IP to an interface and Check Point will detect it, it is normally done through the assignment of NAT".....does that mean i do not need to manually add the ip address in the TCP/IP | properties | IP settings at the OS level?

If you are looking to add a new web server and have it assisgned a stsatic NAT IP, then all you need to do is:

1.  Create new host object for your web server using the internal (LAN) IP
2.  Under the NAT tab, select static NAT and enter the public NAT address you want users to access the web server on
3.  Create a rule to allow web traffic from outside to the web server
4.  Push policy

Thats it bud
