For 10G I would use software NAT like a firewall or CGN virtual 
appliance. Switch ASICs generally don't support NAT well; Tofino and 
maybe Jericho II can probably do it but at high cost and as you 
discovered the market isn't trying very hard to provide "routing" or 
"firewalling" functionality on "switching" ASICs.
