NAT on a 5500G-EI 24-port Superstack Switch

[Lee Payne_1]

Is there a way to configure NAT on a 5500G-EI 24-port Superstack Switch core stack?  I am running 2 VLans, one supporting a public IP range for my desktops and peripherals and one supporting a private 10. network for my VoIP phones.  I need to set up a secure remote access for contracted maintenance services giving them access to all of the 10. network and two servers on my public network.  If NAT is not supported on the 5500G-EI, what would be a workable alternative?

Thanks
