Is it possible to configure Cisco SR520-FE with multiple public IP numbers using static nat

I was hoping to assign an unused IP address from my ISP to a private IP address inside on a new server. I don't see any options in CCA to do this and I was wondering if it was possible using the CLI. I hoped to get some basic feedback before attempting it since it's currently in use.

Thanks in advance.

On an SR520, this is certainly possible from the CLI.  All you need to do is set up the IP nat statement referencing the IP address tha t you want to use and make sure the ACL permits traffic to it.  Do you need an example?

Thanks for the confirmation. What I was thinking was something along these lines...

ip nat inside source static 192.168.x.x xx.xx.xxx.xxx
ip nat outside source static tcp 192.168.x.x 80 xx.xx.xxx.xxx 80

Would I still need an ACL for this?
Jody LemoineNetwork ArchitectCommented:
If you're trying to for ward 80/tcp from the outside to the inside, you should be using an "ip nat inside source static" for both.  You don't *need* an ACL fir either, but if you have ACLs or firewall rules governing your Internet-facing interfaces, you'll need to alter those to accommodate the new NAT statements.
